Router Global Commands
When any of the following events occurs, IGP instructs in the fast path on the IOMs to enable the
LFA backup next-hop:
a. OSPF/IS-IS interface goes operationally down: physical or local admin shutdown.
b. Timeout of a BFD session to a next-hop when BFD is enabled on the OSPF/IS-IS interface
When the SPF computation determines there is more than one primary next-hop for a prefix, it will
not program any LFA next-hop in RTM. Thus, the IP prefix will resolve to the multiple equal-cost
primary next-hops that provide the required protection.
The no form of this command disables the IP FRR feature on the system
Default no ip-fast-reroute
mc-maximum-routes
Syntax mc-maximum-routes number [log-only] [threshold threshold]
no mc-maximum-routes
Context config>router
Description This command specifies the maximum number of multicast routes that can be held within a VPN
routing/forwarding (VRF) context. When this limit is reached, a log and SNMP trap are sent. If the
log-only parameter is not specified and the maximum-routes value is set below the existing number
of routes in a VRF, then no new joins will be processed.
The no form of the command disables the limit of multicast routes within a VRF context. Issue the no
form of the command only when the VPRN instance is shutdown.
Default no mc-maximum-routes
Parameters number — Specifies the maximum number of routes to be held in a VRF context.
log-only — Specifies that if the maximum limit is reached, only log the event. log-only does not
threshold threshold — The percentage at which a warning log message and SNMP trap should be
