Step Command Remarks
2. Define an IPv6
prefix list.
ip ipv6-prefix ipv6-prefix-name [ index index-number ]
{ deny | permit } ipv6-address prefix-length
[ greater-equal min-prefix-length ] [ less-equal
max-prefix-length ]
Not defined by default
NOTE:
If all items are set to the deny mode, no routes can pass the IPv6 prefix list. You must define the permit ::
0 less-equal 128 item following multiple deny items to allow other IPv6 routing information to pass.
For example, the following configuration filters routes 2000:1::/48, 2000:2::/48 and 2000:3::/48, but
allows other routes to pass.
system-view
[Sysname] ip ipv6-prefix abc index 10 deny 2000:1:: 48
[Sysname] ip ipv6-prefix abc index 20 deny 2000:2:: 48
[Sysname] ip ipv6-prefix abc index 30 deny 2000:3:: 16
[Sysname] ip ipv6-prefix abc index 40 permit :: 0 less-equal 128
Defining an AS path list
You can define multiple items for an AS path list that is identified by number. The relation between items
is logical OR. If a route matches one of these items, it passes the AS path list.
To define an AS path list:
Step Command Remarks
1. Enter system view. system-view N/A
2. Define an AS path
ACL. ip as-path as-path-number { deny |
permit } regular-expression
Not defined by default
Defining a community list
You can define multiple items for a community list that is identified by number. During matching, the
relation between items is logic OR. If routing information matches one of these items, it passes the
community list.
To define a community list:
Step Command Remarks
3. Enter system view. system-view N/A
4. Define a community list.
• Define a basic community list:
ip community-list { basic-comm-list-num |
basic comm-list-name } { deny | permit }
[ community-number-list ] [ internet |
no-advertise | no-export |
no-export-subconfed ] *
Use either approach.
