C H A P T E R 14 Border Gateway Protocol (BGP)
265
• Password
To create a new neighbor and include it as a member of the peer
group, use this command:
create bgp neighbor <ip address> peer-group <peer-
group> {multi-hop}
This creates the new neighbor as part of the peer group, and the
neighbor inherits all existing parameters from the peer group. This
command requires the peer group to have remote AS configured.
To add an existing neighbor to a peer group, use this command:
configure bgp neighbor [<ip address>| all] peer-
group <peer-group> {acquire-all}
If you do not specify acquire-all, only the mandatory parameters
are inherited from the peer group. If you specify
acquire-all,
then all the parameters of the peer group are inherited. This
command disables the neighbor before adding the neighbor to the
peer group.
You can display existing peer groups using the command:
show bgp peer-group {detail | <peer-group>
{detail}}
If you specify detail, the parameters of the neighbors in the peer
group that are different from the peer group are displayed.
BGP MD5 Authentication
You can configure MD5 authentication between BGP neighbors.
The maximum length of the password string is 31 characters.
To configure BGP MD5 authentication:
configure bgp neighbor <ip address> password
<password>
To remove BGP MD5 authentication:
configure bgp neighbor <ip address> password none
To show BGP MD5 authentication configuration:
show bgp neighbor detail
