21.2.3 Configuring Distribution Information

Configure the information to be distributed in RAs.

Points to note

To configure the information to be distributed in RAs, switch to interface mode. This section explains how to set the information setting flag (OtherConfigFlag) other than the address by ipv6 nd other-config-flag command, the router priority (DefaultRouterPreference) by ipv6 nd router-preference command, and DNS server information (RDNSS) by ipv6 nd dns-server command.

Command examples

1. (config)# interface vlan 10

   (config-if)# ipv6 nd other-config-flag
