disabled
mode {strict | loose}
no mode
config>router>if>urpf-check
This command specifies the mode of unicast RPF check.
The no form of the command reverts to the default (strict) mode.
strict
strict — When specified, uRPF checks whether incoming packet has a source address that matches a
prefix in the routing table, and whether the interface expects to receive a packet with this source
address prefix.
loose — In loose mode, uRPF checks whether incoming packet has source address with a
corresponding prefix in the routing table. However, the loose mode does not check whether the
interface expects to receive a packet with a specific source address prefix. This object is valid
only when urpf-check is enabled.
[no] mh-primary-interface
config>router
This command creates a loopback interface for use in multihoming resiliency. Once active, this
interface can be used to advertise reachability information to the rest of the network using the
primary address, which is backed up by the secondary.
The reachability for this address is advertised via IGPs and LDP protocols to allow the resolution of
BGP routes advertised with this address.
The no form of the command disables this setting.
no multihoming
