Issue 02 (2014-09-30)
Configuring a BGP4+ Confederation

1.

Run:
system-view
The system view is displayed.
2. Run:
bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
3. Run:
confederation id { as-number-plain | as-number-dot }
The confederation ID is set.
4. Run:
confederation peer-as { as-number-plain | as-number-dot } &<1-32>
The sub-AS number of other EBGP peers connected to the local AS is set.
A confederation includes up to 32 sub-ASs. { as-number-plain | as-number-dot } is
valid for the confederation that it belongs to.
You must run the confederation id and confederation peer-as commands for all the
EBGP peers that belong to a confederation, and specify the same confederation ID for
them.
NOTE
The old speaker with 2-byte AS numbers and the new speaker with 4-byte AS numbers cannot
exist in the same confederation. Otherwise, routing loops may occur because AS4_Path does
not support confederations.
