ZXR10 ZSR V2 Configuration Guide (IPv6)
4.3.5 Example: Configuring FRR for Static IPv6 Route in a Private
Network
Configuration Description
FRR provides backup protection for important nodes or links in the network when they are
invalid to implement fast rerouting, thus minimizing the impact on traffic and restoring traffic
quickly. As shown in
, the FRR function is configured for static IPv6 routes in a
private network.
Figure 4-5 Networking Diagram for Configuring FRR for Static IPv6 Route in a Private
Network
Configuration Flow
1.
Configure VRF, and enable the v6 address family of VRF.
2.
On R1, enable the backup route calculation function for static IPv6 routes in a private
network.
3.
Configure a static IPv6 route as the active route in the private network.
4.
Configure a static IPv6 route as the standby route. Its VRF, destination address, and
mask must be the same with those of the active route. The priority or metric of the
standby route must be lower than that of the active route. The active and standby
routes must have different outgoing interfaces.
Configuration Commands
Configuration on R1:
R1(config)#ip vrf vpn
R1(config-vrf-vpn)#rd 1:3
R1(config-vrf-vpn)#address-family ipv6
R1(config-vrf-vpn-af-ipv6)#route-target 1:1
R1(config-vrf-vpn-af-ipv6)#exit
R1(config-vrf-vpn)#exit
R1(config)#interface gei-1/3
R1(config-if-gei-1/3)#no shutdown
R1(config-if-gei-1/3)#ip vrf forwarding vpn
R1(config-if-gei-1/3)#ipv6 enable
R1(config-if-gei-1/3)#ipv6 address 300::1/56
R1(config-if-gei-1/3)#exit
R1(config)#interface gei-5/1
R1(config-if-gei-5/1)#no shutdown
