Supplying a BGP Router ID
The BGP identifier is the IP address of an interface on the router. When you
enable BGP on the router, you must specify a configured IP address as the router
ID. You can change the router ID to the IP address of another router IP interface.
You can use the BCC or Site Manager to supply a BGP identifier for the router.
Using the BCC
To change the BGP router ID, go to the BGP prompt (for example,
box; ip; /jointfilesconvert/97454/bgp
)
and enter:
router-id
<ip_address>
ip_address
is the address of an IP interface on the router.
For example, the following command specifies IP address 2.2.2.2 for the BGP
router ID:
/jointfilesconvert/97454/bgp#
router-id 2.2.2.2
/jointfilesconvert/97454/bgp#
Using Site Manager
To change the BGP router ID, complete the following steps:
Note:
If both OSPF and BGP are running on the router, the OSPF router ID
and the BGP router ID must be identical. In addition, the router ID must match
one of the IP addresses configured on the router.
