Graceful-Restart Enable - HP 5920 Series Command Reference Manual

gateway prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63
characters, to filter routes by next hop. If you do not specify this option, the command does not filter
routes by next hop.
prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63
characters, to filter routes by destination.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to filter received routes.
Usage guidelines
To reference an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL
in one of the following ways:
To deny/permit a route with the specified destination, use rule [ rule-id ] { deny | permit } ipv6
•
source sour sour-prefix.
• To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit }
ipv6 source sour sour-prefix destination dest dest-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 contiguous. Otherwise, the configuration does not take effect.
Using the filter-policy import command filters only routes computed by OSPFv3. Routes that fail to pass
the filter are not added to the routing table.
Examples
# Use IPv6 prefix list abc to filter received routes.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc permit 2002:1:: 64
[Sysname] ospfv3
[Sysname-ospfv3-1] filter-policy prefix-list abc import
# Configure IPv6 ACL 3000 to permit only route 2001::1/128 to pass. Use ACL 3000 to filter received
routes.
<Sysname> system-view
[Sysname] acl ipv6 number 3000
[Sysname-acl6-adv-3000] rule 10 permit ipv6 source 2001::1 128 destination
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 128
[Sysname-acl6-adv-3000] rule 100 deny ipv6
[Sysname-acl6-adv-3000] quit
[Sysname] ospfv3
[Sysname-ospfv3-1] filter-policy 3000 import
