Configure a BGP Peer or Peer Group Password

Use this procedure to configure a BGP peer or peer group password for Transmission Control Protocol (TCP) MD5 authentication between two peers.

Note

You configure BGP peer on a VRF instance the same way you configure the GlobalRouter, except that you must use VRF Router Configuration mode and the prefix ip bgp. The VRF must have an RP Trigger of BGP. Route refresh is not currently supported on non-default VRFs.

Procedure

Enter BGP Router Configuration mode:

enable

configure terminal

router bgp
Assign a BGP peer or peer group password:

neighbor password <nbr_ipaddr|peer-group=name> WORD <0–1536>

Example

Assign a BGP peer or peer group password:

Switch(router-bgp)# neighbor password peergroupa password1
