Configuring BGP Services
117356-A Rev. A 8-17
Allowing Redundant Connections
By default, BGP performs redundancy checking on peer-to-peer TCP sessions.
BGP can maintain only one TCP session with a remote BGP peer. If the remote
peer attempts to establish another session on another physical connection, BGP
rejects the session. BGP uses a collision-detection method based on router ID to
check for redundant sessions.
The advantage of a peer-to-peer configuration with multiple sessions on multiple
physical connections is redundancy -- if one connection fails, the peers can
communicate over another link. The disadvantage is that such a configuration
results in multiple copies of each route.
You can use the BCC or Site Manager to disable redundancy checking to allow
TCP sessions with the same remote peer on multiple physical connections.
Using the BCC
Navigate to the BGP prompt and enter
redundant-connection
state
state is
enabled (default)
disabled
For example, the following command disables BGP redundancy checking,
allowing BGP to establish multiple TCP sessions (on different physical
connections) with the same remote peer.
