disable isis area adjacency-check

disable isis area area_name adjacency-check {ipv4| ipv6}

Description

This command disables the checking of the following TLVs when forming adjacencies: Protocols Supported and IP Interface Address.

Syntax Description

area_name Specifies the name of the IS-IS router process that should no longer perform the adjacency check.
ipv4 Specifies that the adjacency check should no longer be performed on IPv4 interfaces.
ipv6 Specifies that the adjacency check should no longer be performed on IPv6 interfaces.

Default

IPv4: Enabled.

IPv6: Enabled.

Usage Guidelines

When adjacency checking is disabled, adjacencies may be formed on interfaces that do not reside on the same subnet or do not support IPv4 (if disabled for IPv4) or IPv6 (if disabled for IPv6). If neither ipv4 nor ipv6 is specified, this command applies to IPv4.

Example

The following command directs the IS-IS process named areax to disable adjacency checks on IPv6 interfaces:

disable isis area areax adjacency-check ipv6
