29.6.1 Checking BGP4 and peer groups

<Structure of this section>

(1) List of operation commands

The following tables list the operation commands for BGP4 + peer groups.

Table 29-19: List of operation commands
Command name	Description
show ipv6 bgp	Shows information about the BGP4+ protocol.

(2) Checking BGP4 and peer groups

To check the peering information about the peers in a peer group, use the show ipv6 bgp command with the peer-group parameter specified.

(3) Checking the peers that belong to BGP4 + peer group

To display information about the peers in a peer group, use the show ipv6 bgp command with the neighbors parameter and the peer-group or detail parameter specified.

(4) Checking BGP4 to which the peer belongs + the peer group

To check which peer group a peer belongs to, use the show ipv6 bgp command with the neighbors parameter and a <Peer Address> or <Host name> argument specified.
