Disabling an interface from sending/receiving IS-IS packets
After being disabled from sending and receiving hello packets, an interface cannot form any neighbor
relationship, but can advertise directly connected networks in LSPs through other interfaces. This can save
bandwidth and CPU resources, and ensures other routers know networks directly connected to the
interface.
To disable an interface from sending and receiving IS-IS packets:

isis silent Not disabled by default.
Disabling hello source address check for a PPP interface
On a P2P link, IS-IS verifies the source IP address of the incoming hello packets is in the same network
segment as the IP address of the receiving interface. If not, it discards the hello packets, and no neighbor
relationship can be established with the peer router.
If a PPP interface's peer IP address is on a different network segment, disable the hello source address
check for the PPP interface to establish the neighbor relationship with the peer.
To enable neighbor relationships over different network segments:

The command only applies to the PPP
interface.

is enabled.
