R3303-HP HSR6800 Routers Layer 3 - IP Routing Command Reference

167
Usage guidelines
Do not use FRR and BFD at the same time. Otherwise, FRR might fail to take effect.
The automatic backup next hop calculation of FRR and that of TE are mutually exclusive.
Example
# Enable IS-IS FRR to automatically calculate a backup next hop for all routes.
<Sysname> system-view
[Sysname] bfd echo-source-ip 1.1.1.1
[Sysname] isis
[Sysname-isis-1] fast-reroute auto
# Enable IS-IS FRR to designate a backup next hop by using a referenced routing policy named frr.
<Sysname> system-view
[Sysname] bfd echo-source-ip 1.1.1.1
[Sysname] ip ip-prefix abc index 10 permit 100.1.1.0 24
[Sysname] route-policy frr permit node 10
[Sysname-route-policy] if-match ip-prefix abc
[Sysname-route-policy] apply fast-reroute backup-interface gigabitethernet 2/1/1
backup-nexthop 193.1.1.8
[Sysname-route-policy] quit
[Sysname] isis 100
[Sysname-isis-100] fast-reroute route-policy frr
filter-policy export (IS-IS view)
Use filter-policy export to configure IS-IS to filter redistributed routes.
Use undo filter-policy export to disable IS-IS from filtering redistributed routes.
Syntax
[ ipv4-unicast topology-name ] filter-policy { acl-number | ip-prefix ip-prefix-name | route-policy
route-policy-name } export [ protocol [ process-id ] ]
undo [ ipv4-unicast topology-name ] filter-policy export [ protocol [ process-id ] ]
Default
IS-IS does not filter redistributed routes.
Views
IS-IS view
Default command level
2: System level
Parameters
ipv4-unicast: Specifies an IPv4 unicast topology. If no topology is specified, the routes redistributed from
the base topology is filtered.
topology-name: Specifies a topology by its name, a case-sensitive character string of 1 to 31 characters.
acl-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter redistributed routes. For
ACL configuration information, see ACL and QoS Command Reference.
