Router-id
=========
Many routing protocols require a router-id to be configured. To have a
consistent router-id across all daemons, the following commands are available
to configure and display the router-id:
.. index:: [no] router-id A.B.C.D [vrf NAME]
.. clicmd:: [no] router-id A.B.C.D [vrf NAME]
Configure the router-id of this router.
.. index:: show router-id [vrf NAME]
.. clicmd:: show router-id [vrf NAME]
Display the user configured router-id.
