Context config>router
Description
This command creates a loopback interface for use in multihoming resiliency. This address is
considered the secondary multihoming address and is only used to resolve routes advertised by the
primary router in the event that router becomes unavailable. For this purpose, the reachability for this
address is advertised via IGPs and LDP protocols to allow the resolution of BGP routes advertised
with this address by the primary multihoming router.
The no form of the command disables this setting.
Default
no mh-secondary-interface
hold-time
Syntax hold-time holdover-time
no hold-time
Context config>router>mh-secondary-interface
Description The optional hold-time parameter is only applicable for the secondary context and specifies how long
label information leraned about the secondary anycast address should be kept after that peer is
declared down. This timer should be set to a value large enough for the remainder of the network to
detect the failure and complete the reconvergence process.
The no form of the command resets the hold-time back to the default value.
Default
no hold-time
Parameters holdover-time — Specifies the number of seconds the router should hold label information learned

from the alternate router in its secondary label table. This is to allow the reset of the network to
reconverge after a router failure before the anycast based label assignments are flushed from the
forwarding plane.
