R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

713
ipv6-prefix ipv6-prefix-name: Specifies the name of an IPv6 prefix list to filter incoming routes, in the
range of 1 to 19 characters.
Description
Use filter-policy import to define an inbound route filtering policy. Only routes which match the filtering
policy can be received.
Use undo filter-policy import to disable inbound route filtering.
By default, RIPng does not filter incoming routing information.
NOTE:
If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, the ACL
should be configured with the rule [
rule-id ] { deny | permit } ipv6 source sour sour-prefix command to
deny/permit a route with the specified destination, or with the rule [
rule-id ] { deny | permit } ipv6 source
sour sour-prefix destination dest dest-prefix command to deny/permit a route with the specified
destination and prefix. The source keyword specifies the destination address of a route and the
destination keyword specifies the prefix of the route (the prefix must be valid; otherwise, the confi
g
uration
is ineffective).
