configure ospfv3 area interarea-filter

Description

Configures an inter-area filter policy.

Syntax Description

Default

N/A.

Usage Guidelines

ExtremeXOS OSPFv3 can apply an inter-area policy to filter some inter-area-prefix-LSAs and inter-area-router-LSAs from other areas. This can reduce the size of link state database of routers belonging to the area.

Using the none mode specifies that no external filter is applied.

Any other policy attribute will not be recognized and will be ignored.

The following is an example of an inter-area filter policy file:

entry one {
	if match any{
		nlri 2001:db8:3e5c::/48;
		nlri 2001:db8:2146:2341::/64;
	} then {
		deny;
	}
}
entry two {
	if match any{
		nlri 2001:db8:444::/48;
		nlri 2001:db8:541f:65bd::/64;
	} then {
		permit;
	}
}
