Syntax mode {strict | loose | strict-no-ecmp}
no mode
Context config>router>if>urpf-check
config>router>if>>ipv6>urpf-check
Description This command specifies the mode of unicast RPF check.
The no form of the command reverts to the default (strict) mode.
Default strict
Parameters 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.
strict-no-ecmp — When a packet is received on an interface in this mode and the SA matches an
ECMP route the packet is dropped by uRPF.
mh-primary-interface
Syntax [no] mh-primary-interface
Context config>router
Description 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.
Default no multihoming
address
Syntax address {ip-address/mask | ip-address netmask}
