IP Router Configuration
Router Configuration Guide 121
Description This command selects the CPM network processor as the local termination point for the BFD session.
This is enabled by default.
Default type cpm-np
single-sfm-overload
Syntax single-sfm-overload [holdoff-time holdoff-time]
no single-sfm-overload
Context config>router
Description This command configures OSPF, OSPFv3 and IS-IS to set overload when the router has fewer than the
full set of SFMs functioning, which reduces forwarding capacity. Setting overload enables a router to
still participate in exchanging routing information, but routes all traffic away from it.
The conditions to set overload are as follows:
• 7750 SR-12/SR-7/SR-c12 and 7450 ESS-12/ESS-7/ESS-6 platforms: protocol sets overload
if one of the SF/CPMs fails
• 7950 XRS and 7750 SR-12e platforms: protocol sets overload if two SFMs fail
The no form of this command configures the router to not set overload if an SFM fails.
Default no single-sfm-overload
Parameters holdoff-time — This parameter specifies the delay between detecting SFM failures and setting
overload.
Values 1to 600 seconds
Default 0 seconds
static-route-entry
Syntax static-route-entry {ip-prefix/prefix-length} [mcast]
Context config>router
Description This command creates a static route entry for both the network and access routes. A prefix and netmask
must be specified.
Once the static route context for the specified prefix and netmask has been created, additional
parameters associated with the static route(s) may be specified through the inclusion of additional
static route parameter commands
The no form of the command deletes the static route entry. If a static route needs to be removed when
multiple static routes exist to the same destination, then as many parameters to uniquely identify the
static route must be entered
