Parameters
as-number-list: Sub-AS number list. Up to 32 sub-ASs can be configured in one
command line. The expression is as-number-list = as-number &<1-32>, in which
as-number specifies a sub-AS number, and &<1-32> indicates up to 32 numbers can
be specified.
Description
Use the confederation peer-as command to specify confederation peer sub-ASs.
Use the undo confederation peer-as command to remove specified confederation
peer sub-ASs.
By default, no confederation peer sub-ASs are configured.
Before this configuration, the confederation id command must be used to specify the
confederation for the sub-ASs.
If the undo confederation peer-as command without the as-number-list argument is
used, all confederation peer sub-ASs are removed.
Related commands: confederation nonstandard and confederation id.
Examples
# Specify confederation peer sub ASs 2000 and 2001.
