Configure network layer addresses for interfaces to make neighboring nodes accessible to each

other at the network layer.

Enable IS-IS.

Configuring Neighbor Relationship Authentication

With neighbor relationship authentication configured, an interface adds the password in the specified

mode into hello packets to the peer and checks the password in the received hello packets. If the

authentication succeeds, it forms the neighbor relationship with the peer.

The authentication mode and password at both ends must be identical.

Follow these steps to configure neighbor relationship authentication:

To do…

Use the command…

Remarks

Enter interface view

interface interface-type

interface-number

––

Specify the authentication mode

and password

isis authentication-mode { md5 |

simple } password [ level-1 | level-2 ] [ ip

| osi ]

Required

Not authentication is

configured by default.

Configuring Area Authentication

Area authentication enables a router not to install routing information from untrusted routers into the

Level-1 LSDB. The router encapsulates the authentication password in the specified mode into Level-1

packets (LSP, CSNP, PSNP) and check the password in received Level-1 packets.

Routers in a common area must have the same authentication mode and password.

Follow these steps to configure area authentication:

To do…

Use the command…

Remarks

Enter IS-IS view

isis [ process-id ] [ vpn-instance

––

Specify the area authentication

mode and password

area-authentication-mode { md5 |

simple } password [ ip | osi ]

Required

No area authentication is

configured by default.

Configuring Routing Domain Authentication

Routing domain authentication prevents untrusted routing information from entering into a routing

domain. A router with the authentication configured encapsulates the password in the specified mode

into Level-2 packets (LSP, CSNP, PSNP) and check the password in received Level-2 packets.
