Usage Guidelines
ExtremeWare XOS 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.
Policy files for this command will only recognize the following policy attributes:
Match attributes
●
nlri <IPv6-address>/<mask-len>
■
Action (set) attributes
●
permit
■
deny
■
Any other policy attribute will not be recognized and will be ignored.
The following is an example of an external area policy file:
entry one {
if match any{
nlri 2001:db8:3e5c::/48;
nlri 2001:db8:2146:2341::/64;
