Network requirements
As shown in
, branch nodes Router B through Router H are uplinked to the central node
Router A through E1 links. Router A aggregates these E1 links by using a CPOS interface.
Add one additional E1 link on Router B to expand its capacity, and use an MP-group interface to bind
the two E1 links.
