Example-Conguring BGP routing between peers
Example of enabling BGP in Router A
Following is an example to enable BGP conguration in the router A.
RouterA# configure terminal
RouterA(conf)# router bgp 40000
RouterA(conf-router_bgp)# bgp router-id 10.1.1.99
RouterA(conf-router_bgp)# timers bgp 80 130
RouterA(conf-router_bgp)# neighbor 192.168.1.1 remote-as 45000
RouterA(conf-router_bgp)# exit
RouterA(conf)#
The neighbors congured under CONFIGURATION-ROUTER-BGP mode and are dened using the neighbor remote-as command
exchange only IPv4 unicast address prexes.
Example of enabling BGP in Router B
Following is an example to enable BGP conguration in the router B.
RouterB# configure terminal
RouterB(conf)# router bgp 45000
RouterB(conf-router_bgp)# bgp router-id 172.17.1.99
RouterB(conf-router_bgp)# timers bgp 70 120
RouterB(conf-router_bgp)# neighbor 192.168.1.2 remote-as 40000
RouterB(conf-router_bgp)# exit
RouterB(conf)#
The show ip bgp summary displays BGP conguration. Following is the sample output for show ip bgp summary command for
router A.
RouterA#show ip bgp summary
BGP router identifier 10.1.1.99, local 40000

Following is the sample output for show ip bgp summary command for Router B.
RouterB#show ip bgp summary
BGP router identifier 172.17.1.99, local 45000
BGP local RIB : Routes to be Added 0, Replaced 0, Withdrawn 0

BGP peer group
To congure multiple BGP neighbors at one time, create and populate a BGP peer group.
If you want to congure multiple BGP neighbors with similar policies (route maps, distribute lists, and so on), you can group the respective
neighbors under a peer group. A peer group contains a set of BGP neighbors which share common congurations. You can group neighbors
that share congurations in a BGP peer group to simplify neighbor conguration. An advantage of peer groups is that members of a peer
group inherit the conguration properties of the group and share same update policy.
Dell EMC Networking OS allows a maximum of 256 peer groups.
