Table 6-38 Configuring sub-AS belonging to the confederation
Configure a confederation consisting of
which sub-ASs
Cancel the specified sub-AS in the
confederation
By default, no autonomous system is configured as a member of the confederation.
III. Configuring the autonomous system confederation nonstandard
If it is necessary to perform the interconnection with the devices whose implementation
mechanism is different from that of RFC1965, you must configure all the routers in the
confederation.
Perform the following configurations in BGP view.
Table 6-39 Configuring AS confederation attribute compatible with nonstandard
Configure AS confederation attribute
compatible with nonstandard router
Cancel
compatible with nonstandard router
By default, the configured confederation is consistent with RFC1965.
6.2.18 Defining ACL, AS Path List, and Route-policy
This section describes the configuration of ACL, AS path list, and Route-policy.
I. Defining the ACL
Refer to "Define ACL" in QoS/ACL Operation Manual and Command Manual.
II. Defining the AS path list
The routing information packet of the BGP includes an autonomous system path
domain. The as path-list can be used to match with the autonomous system path
domain of the BGP routing information so as to filter the routing information, which does
not conform to the requirements. For the same list number, the user can define multiple
pieces of as path-list, i.e. a list number stands for a group of as path ACLs. Each AS
path list is identified with digit.
