Advertise Routes with Looped
AS Path to ver 3 Peers Prevents routes with looped autonomous system
paths from being advertised to version 4 external
peers. This can be useful when trying to avoid
advertising routes to peers that would automatically
(and erroneously) forward routes on to version 3
neighbors.
Advertise Routes with Looped
AS Path to ver 4 Peers Instructs the SSR to log an informational message
whenever an associated peer’s state changes.
Log Message Whenever BGP
Peer Changes State Specifies that the next hop in route advertisements
for this peer or group of peers is to be this SSR, even
if it would normally be possible to send a third-
party next hop. This option may be useful in cases
that deal with broken bridged interconnect media
(in cases where the routers on the shared medium
do not really have full connectivity to each other) or
broken political situations.
Note:
This option may cause inefficient routes to
be followed. Cabletron recommends that
you use this option only for external groups.
