Step 5 Configure MPLS LDP GR of the backbone network.
Configure MPLS LDP GR on PE1, P device, and PE2 on the backbone network.
# Configure PE1.
[PE1] mpls ldp
[PE1-mpls-ldp] graceful-restart
[PE1-mpls-ldp] quit
# Configure the P device.
[P] mpls ldp
[P-mpls-ldp] graceful-restart
[P-mpls-ldp] quit
# Configure PE2.
[PE2] mpls ldp
[PE2-mpls-ldp] graceful-restart
[PE2-mpls-ldp] quit
Step 6 Configure GR of routing protocols between PEs and CEs.
Configure BGP GR for BGP between PE1 and CE1 and configure OSPF GR for OSPF between
PE2 and CE2
# Configure PE1.
[PE1] bgp 100
[PE1-bgp] graceful-restart
[PE1-bgp] quit
# Configure CE1.
[CE1] bgp 65410
[CE1-bgp] graceful-restart
[CE1-bgp] quit
# Configure PE2.
[PE2] ospf 2 vpn-instance vpn1
[PE2-ospf-2] opaque-capability enable
[PE2-ospf-2] graceful-restart
[PE2-ospf-2] quit
# Configure CE2.
[CE2] ospf 2
[CE2-ospf-2] opaque-capability enable
[CE2-ospf-2] graceful-restart
[CE2-ospf-2] quit
