Border Gateway Protocol IPv4 (BGPv4) | 233
When you add a peer to a peer group, it inherits all the peer group’s configured parameters.
A neighbor
cannot
become part of a peer group if it has any of the following commands are configured:
• neighbor advertisement-interval
• neighbor distribute-list out
• neighbor filter-list out
• neighbor next-hop-self
• neighbor route-map out
• neighbor route-reflector-client
• neighbor send-community
A neighbor may keep its configuration after it was added to a peer group if the neighbor’s configuration is
more specific than the peer group’s, and the neighbor’s configuration does not affect outgoing updates.
Use the
show config
command in the CONFIGURATION ROUTER BGP mode to view the
configuration. When you create a peer group, it is disabled (
shutdown
). Figure 10-19 shows the creation
of a peer group (zanzibar).
Figure 10-19. Command example:
show config
(creating peer-group)
Use the neighbor peer-group-name no shutdown command in the CONFIGURATION ROUTER BGP
mode to enable a peer group.
Note: When you configure a new set of BGP policies for a peer group,
always
reset the peer
group by entering the
clear ip bgp peer-group
peer-group-name
command in EXEC Privilege mode.
