My company is changing its MPLS carrier. I need to change the BGP AS number of an in-house router, NetVanta 3430 with OS version 18.01.01, to work with new carrier router. My current BGP configuration is as follows,
!
router bgp 65001
no auto-summary
no synchronization
bgp router-id 192.168.1.1
network 192.168.1.0 mask 255.255.255.0
neighbor 10.100.100.1
no default-originate
soft-reconfiguration inbound
remote-as 65000
!
I need to change it to:
!
router bgp 65000
no auto-summary
no synchronization
bgp router-id 192.168.1.1
network 192.168.1.0 mask 255.255.255.0
neighbor 10.100.100.1
no default-originate
soft-reconfiguration inbound
remote-as 65001
!
You can only have one AS on a router at a time. You'll need to remove the BGP configuration and re-add it. "No out" the old BGP configuration and then you can implement the new one. Something like this should work:
no router bgp 65001
!
router bgp 65000
no auto-summary
no synchronization
bgp router-id 192.168.1.1
network 192.168.1.0 mask 255.255.255.0
neighbor 10.100.100.1
no default-originate
soft-reconfiguration inbound
remote-as 65001
!
Obviously, don't do this remotely over the BGP network or you'll lock yourself out.
