Padmashree, Thanks for your reply. I think I found a few things out which might help the community...some might not.
The ultimate cure was to add:
configure bgp add network SMALLERSUB/NET
modify aggregate address to remove SMALLERSUB/NET from aggregation:
configure bgp add aggregate-address LARGERSUB/NET summary-only advertise-policy RemoveSummary
edit RemoveSummary.pol
entry removefromsummary {
if match any {
nlri SMALLERSUB/NET exact;
} then {
deny;
}
}
entry accept_others {
if { } then {
permit;
}
}
Last but not least, one of my routers was routers was kicking out the route received from an ebgp peer..haven't had the time to look at release notes but I suspect it is a previously addressed bug.
Hope this info helps somebody!
