To support your own IP addresses, interfaces, names, and so on, you can copy and paste from these examples to your CLI. Be
sure that you make the necessary changes.
Example-Configuring BGP routing between peers
Example of enabling BGP in Router A
Following is an example to enable BGP configuration 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 configured under CONFIGURATION-ROUTER-BGP mode and are defined using the neighbor remote-as
command exchange only IPv4 unicast address prefixes.
Example of enabling BGP in Router B
Following is an example to enable BGP configuration 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 configuration. 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
BGP local RIB : Routes to be Added 0, Replaced 0, Withdrawn 0
1 neighbor(s) using 40960 bytes of memory

192.168.1.1 45000 10 20 0 0 0 00:06:11 0
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BGP local RIB : Routes to be Added 0, Replaced 0, Withdrawn 0
1 neighbor(s) using 40960 bytes of memory

192.168.1.2 40000 10 20 0 0 0 00:06:11 0
BGP peer group
To configure multiple BGP neighbors at one time, create and populate a BGP peer group.
If you want to configure 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 configurations.
You can group neighbors that share configurations in a BGP peer group to simplify neighbor configuration. An advantage of peer
groups is that members of a peer group inherit the configuration properties of the group and share same update policy.
Dell EMC Networking OS allows a maximum of 256 peer groups.
Tasks involved in configuring a BGP peer group:
● Create a peer group by assigning it a name
● Adding members (neighbors) to the peer group
Configuration rules in a peer group:
Border Gateway Protocol (BGP)
