If a peer group is not configured with a remote-as attribute, the members can be
configured with the neighbor remote-as (BGP and BGP4+) command in Router
Configuration mode. This command allows you to create peer groups containing external
BGP (eBGP) neighbors.
You can customize inbound policies for peer group members (using a distribute list, a
route map, or a filter list) because one identical copy of an update is sent to every member
of a group. Neighbor options for outgoing updates cannot be customized for peer groups.
External BGP (eBGP) peers must reside on a directly connected network. But you may want
to change this to test BGP or BGP4+. You can do this by specifying the neighbor ebgp-
multihop (BGP and BGP4+) command in Router Configuration mode. Members of a peer
group can pass routes from one member of the peer group to another. For example, if
router B is peering with routers A and C, router B can pass routes from router A to router C.
For Internal BGP (iBGP) peers, you may want to allow BGP or BGP4+ connections to stay up
if any interface is used. To enable this configuration, configure a loopback interface and
assign it an IPv4 or an IPv6 address. Next, configure the BGP or BGP4+ update source to be
the loopback interface. Then configure your neighbor to use the address on the loopback
interface. Now the iBGP session will be up as long as there is a route on any interface.
awplus(config-router)#
neighbor <neighborid>
next-hop-self
This command disables next hop processing on the BGP
updates to a neighbor.
awplus(config-router)#
neighbor <neighborid> version
<version>
This command specifies the BGP version to use when
communicating with a neighbor.
awplus(config-router)#
neighbor {<ip-address>|
<peer-group-name>} password
<password>
This command starts MD5 authentication on a TCP connection
to a BGP peer. You can enter a case-sensitive password of up to
25 characters. The string can contain any alphanumeric
characters.
awplus(config-router)#
neighbor <neighborid> route-map
<mapname> {in|out}
This command applies a route map to incoming or outgoing
routes.
awplus(config-router)#
neighbor <neighborid>
soft-reconfiguration inbound
This command configures the software to start storing received
updates.
