2. Configure the
source address of
echo packets.
bfd echo-source-ip ip-address
Not configured by default.
For more information about
this command, see High
Availability Command
Reference.
3. Enable BFD echo
mode for static
routes.
• Approach 1:
ip route-static dest-address { mask |
mask-length } interface-type interface-number
next-hop-address bfd echo-packet [ preference
preference-value ] [ tag tag-value ] [ description
description-text ]
• Approach 2:
ip route-static vpn-instance
s-vpn-instance-name&<1-6> dest-address { mask
| mask-length } interface-type interface-number
next-hop-address bfd echo-packet [ preference
preference-value ] [ tag tag-value ] [ description
description-text ]
Use either approach.
Configuring static route FRR
NOTE:
Only the A5500 EI Switch Series supports static route FRR.
A link or router failure on a path can cause packet loss and even routing loop. Static route fast reroute
(FRR) enables fast rerouting to minimize the impact of link or node failures.
Figure 1 Network diagram
As shown in Figure 1, upon a link failure, FRR designates a backup next hop by using a routing policy for
routes matching the specified criteria. Packets are directed to the backup next hop to avoid traffic
interruption.
Configuration prerequisites
Configuring static route FRR needs to reference a routing policy. You can specify a backup next hop in
a routing policy by using the apply fast-reroute backup-interface command. For more information about
the command and routing policy configurations, see "Configuring routing policies."
