[Explanation of message variables] <mask>: Routing information network mask <destination address>: Routing information destination address <source address>: Source gateway <vrf id> VRF ID [Action] Check the unicast routing program (RIP) for the source gateway.
3	rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - ignoring version 0 packets	Error (remote device)
3		A received RIP packet was ignored because the version field is 0. [Explanation of message variables] <rip command>: Received message type Invalid, Request, Response, TraceOn, TraceOff, Poll, PollEntry <source address>: Source gateway <vrf id> VRF ID [Action] Check the unicast routing program (RIP) for the source gateway.
4	rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - reserved field not zero	Error (remote device)
4		A received RIP packet was ignored because the reserved field is not 0. [Explanation of message variables] <rip command>: Received message type Invalid, Request, Response, TraceOn, TraceOff, Poll, PollEntry <source address>: Source gateway <vrf id> VRF ID [Action] Check the unicast routing program (RIP) for the source gateway.
5	rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - authentication failure [(Key-ID <key id>)]	Error (local or remote device)
5		A received RIP packet was ignored because of an authentication error. This operation message is output according to the following conditions: The messages from the first to the 16th event are output. After 17 times from the beginning of the event occurrence, this message is output once every 256 times the event occurs. If an event occurs 3 minutes or more after the last event occurred, this message is output depending on 1 and 2 above. Note that the above number of messages includes the count of the following messages: rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication type rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication key identifier (Key-ID <key id>) rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication sequence number (Key-ID <key id>) [Explanation of message variables] <rip command>: Received message type Invalid, Request, Response, TraceOn, TraceOff, Poll, PollEntry <source address>: Source gateway <vrf id> VRF ID <key id>: Key identifier [Action] Check whether the authentication key for the local device RIP matches the authentication key for the remote device RIP. If they do not match, specify the authentication keys so that they do match.
6	rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - TRACE packets not supported	Warning (remote device)
6		A received RIP packet was ignored because TRACE packets are not supported. [Explanation of message variables] <rip command>: Received message type TraceOn, TraceOff <source address>: Source gateway <vrf id> VRF ID [Action] Check the specifications of the unicast routing program (RIP) for the source gateway.
7	rip_init: Old copy of rtm is running	Error (local device)
7	rip_init: Old copy of rtm is running	Unicast routing program might already be running. The unicast routing program automatically restarts. [Explanation of message variables] None. [Action] Take appropriate action by following the rtm aborted log.
8	RIP: The total number of RIP targets is more than the maximum permitted	Error (local device)
8		The total number of RIP targets (adjacent) exceeds the maximum number permitted. [Explanation of message variables] None. [Action] Check, and if necessary, revise the RIP settings so that the maximum number of adjacent routers does not exceed the capacity limit.
9	rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication type	Error (remote device)
9		A received RIP packet was ignored because the authentication type of authentication information is invalid. This operation message is output according to the following conditions: The messages from the first to the 16th event are output. After 17 times from the beginning of the event occurrence, this message is output once every 256 times the event occurs. If an event occurs 3 minutes or more after the last event occurred, this message is output depending on 1 and 2 above. Note that the above number of messages includes the count of the following messages: rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - authentication failure [(Key-ID <key id>)] rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication key identifier (Key-ID <key id>) rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication sequence number (Key-ID <key id>) [Explanation of message variables] <rip command>: Received message type Invalid, Request, Response, TraceOn, TraceOff, Poll, PollEntry <source address>: Source gateway <vrf id> VRF ID [Action] Check the unicast routing program (RIP) for the source gateway.
10	rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication key identifier (Key-ID <key id>)	Error (local or remote device)
10		A received RIP packet was ignored because the key identifier of authentication information was invalid. This operation message is output according to the following conditions: The messages from the first to the 16th event are output. After 17 times from the beginning of the event occurrence, this message is output once every 256 times the event occurs. If an event occurs 3 minutes or more after the last event occurred, this message is output depending on 1 and 2 above. Note that the above number of messages includes the count of the following messages: rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - authentication failure [(Key-ID <key id>)] rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication type rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication sequence number (Key-ID <key id>) [Explanation of message variables] <rip command>: Received message type Invalid, Request, Response, TraceOn, TraceOff, Poll, PollEntry <source address>: Source gateway <vrf id> VRF ID <key id>: Key identifier [Action] Check whether the key identifier of authentication information for the local device RIP matches the key identifier of authentication information for the remote device RIP. If they do not match, specify the key identifiers so that they do match.
11	rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication sequence number (Key-ID <key id>)	Error (remote device)
11		A received RIP packet was ignored because the sequence number of authentication information was invalid. This operation message is output according to the following conditions: The messages from the first to the 16th event are output. After 17 times from the beginning of the event occurrence, this message is output once every 256 times the event occurs. If an event occurs 3 minutes or more after the last event occurred, this message is output depending on 1 and 2 above. Note that the above number of messages includes the count of the following messages: rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - authentication failure [(Key-ID <key id>)] rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication type rip_recv: Ignoring RIP <rip command> packet from <source address> [(VRF <vrf id>)] - illegal authentication key identifier (Key-ID <key id>) [Explanation of message variables] <rip command>: Received message type Invalid, Request, Response, TraceOn, TraceOff, Poll, PollEntry <source address>: Source gateway <vrf id> VRF ID <key id>: Key identifier [Action] Check the unicast routing program (RIP) for the source gateway.
