DES-7200 Configuration Guide Chapter 6 BGP
Configuration
6-33
Caution
The restart time configured by the bgp graceful-restart restart-time command
should be no more than the Hold time of the BGP peer, or otherwise the Hold
Time will be used as the restart time and be notified to the peer for GR
capability negotiation.
6.21 Configuring BGP Multicast
The BGP multicast route is used for multicast RFC check. In general, the
multicast forwarding topology can be similar to the unicast forwarding topology.
You can design different multicast topology by using BGP multicast, which is used
for multicast topology between ASs, as shown in the following figure.
There are two routers in AS100. In design, unicast streams are sent to R1 and
multicast streams are sent to R2. In this case, MPBGP is necessary between R2
and R3.
Step 1: Enable BGP on R1, R2 and R3 and establish neighbor relationships
among them.
Take R3 as an example. Configure R1 and R2 as its BGP neighbors.
Command Function
DES-7200 # configure terminal Enter the global configuration mode.
DES-7200(config)# router bgp 200
Enter the BGP configuration mode
with the AS number of 200.
