Configuration Roadmap
The configuration roadmap is as follows:
1. Configure BGP/MPLS IP VPN.
2. Configure IGP GR of the backbone network.
3. Configure MPLS LDP GR of the backbone network.
4. Configure GR of routing protocols between PEs and CEs.
5. Configure BGP GR.
Data Preparation
To complete the configuration, you need the following data:
l VPN instance name, Router Distinguisher (RD), and VPN target
l Interval for IS-IS to reestablish GR sessions (this example retains the default value, that is,
300 seconds)
l Time for reestablishing MPLS LDP sessions (this example retains the default value, that
is, 300 seconds) and value of the neighbor-liveness timer (this example retains the default
value, that is, 600 seconds)
l BGP-allowed maximum interval for the peer end to reestablish GR sessions (this example
retains the default value, that is, 150 seconds)
l Time for waiting for End-of-RIB messages (this example retains the default value, that is,
600 seconds)
l Data of the routing protocols between PEs and CEs (in this example, BGP is run between
CE1 and PE1 and OSPF is run between CE2 and PE2)
l Data required for configuring IGP of the backbone network (this example uses IS-IS)
Procedure
Step 1 Create VLANs and add interfaces to the VLANs.
