A similar peer group is created on R4 to peer with R5. Example 8-97 shows the new
configurations on R4.
Example 8-97

Step 7: On R1 and R2, Update the Peerings with R5 and Put R5 Back in the
Forwarding Paths
You need to update configurations on R1 and R2 to peer with R5. Example 8-98 shows the
new BGP configurations on R1. Similar changes are made to R2 (not shown). Now you can
put R5 back in the forwarding paths.
Example 8-98
New BGP Configurations on R1
router bgp 65000
no synchronization
bgp router-id 192.168.100.1
bgp log-neighbor-changes
bgp confederation identifier 100
bgp confederation peers 100 65001
