Hi,
We are redistributing our own prefixes via iBGP with redist connected + static with route-map :
router bgp AAAA
address-family ipv4
redistribute connected route-map OUR_RANGES
redistribute static route-map OUR_RANGES
route-map OUR_RANGES permit 10
match ip address prefix-list PL_OUR_RANGES
set community AAAA:1000 AAAA:1301 AAAA:14000
ip prefix-list PL_OUR_RANGES seq 5 permit XXX.XXX.XXX.0/20 le 32
Which is working fine - but advertisement of the aggregate/supernet to our upstreams is not allowing prepending of as? (Have performed clear ip bgp nei_ip)
Is it because the prefixes are seen as Origin incomplete vs Origin IGP?
router bgp AAAA
address-family ipv4
neighbor UPSTREAM_A_IPTRANSIT route-map UPSTREAM_A_OUT_OUT out
route-map UPSTREAM_A_OUT_OUT permit 30
match ip address prefix-list PL_OUR_PREFIXES_OUT
set as-path prepend AAAA
#sh ip bgp neighbors WWW.WWW.WWW. advertised-routes

#sh ip bgp route-map UPSTREAM_A_OUT_OUT

* i YYY.YYY.YYY.218 0 100 0 ?
*>i YYY.YYY.YYY.218 0 100 0 ?
Thanks in advance.
