BGP GR configuration example

Network requirements

All switches run BGP in Figure 96. Between Switch A and Switch B is an EBGP connection. Switch B and

Switch C are connected over an IBGP connection. Enable GR capability for BGP so that the

communication between Switch A and Switch C is not affected when a master/slave switchover occurs

on Switch B.
