Hi,
Thanks for the reply - route-map show its getting a hit for the supernet (And redist statements are not new unfortunately) - The route is in bgp table, and being advertised to upstreams.....just not to our RRs....I did some further checking post identifying the "no community tag" issue - It seems all "other" static and connected routes are being tagged with the correct communities (And therefore, and being advertised to our RRs(route-map filters based on community tag).....Ive had a bit of a google, but found nothing (yet)....but is this "normal" behavior for a Cisco? To not tag static routes to Null0 with communities.....seems very odd, but all other static routes/and connected are being tagged.....just not the supernet? Thanks in advance. ________________________________ From: Mattias Gyllenvarg <matt...@gyllenvarg.se> Sent: Tuesday, 26 September 2017 4:32 PM To: CiscoNSP List; cisco-nsp@puck.nether.net Subject: Re: [c-nsp] BGP not advertising supernet to RR's You can test the hits in the route-map with "sh ip bgp route-map G----_RANGES" and see if it hits correctly. If the redist statements are new then they will take time to be implemented, 20min I think for a full BGP rerun. If you are in a hurry, remove and re add the route. Do you receive this route via BGP aswell? Perhaps this is not the best route as BGP sees it. tis 26 sep. 2017 kl 08:10 skrev CiscoNSP List <cisconsp_l...@hotmail.com<mailto:cisconsp_l...@hotmail.com>>: Hi Everyone, Have a problem with supernet being advertised from an ASR1006 to our RR's - Prefix is in the routing table, and in bgp, but the router is only advertising smaller prefixes to the RR's (/30,/29, 28 etc)...I dont *think* its due to the PL (As it should be allowing anything less that /32...which it appears to be doing as /30,/29 etc are being advertised?) Appreciate any assistance. ** Ah - Update, just noticed as I was about to hit send that the supernet is not being tagged with any community.....smaller prefixes are though? So route-map is tagging "some" prefixes within the supernet? router bgp 1***6 address-family ipv4 redistribute connected route-map G----_RANGES redistribute static route-map G----_RANGES neighbor xxx.xxx.76.204 route-map TO_ME1_RR out route-map TO_ME1_RR permit 10 match community CL_G----_RANGES route-map TO_ME1_RR permit 20 match community CL_G----_CUST_BGP_RANGES route-map TO_ME1_RR permit 30 match community CL_DEFAULT_ROUTE ip community-list standard CL_G----_RANGES permit 1***6:1301 ip community-list standard CL_G----_RANGES permit 1***6:1302 route-map G----_RANGES permit 10 match ip address prefix-list PL_G----_PREFIXES set community 1***6:1000 1***6:1301 1***6:11000 route-map G----_RANGES permit 20 match ip address prefix-list PL_N***S_PREFIXES set community 1***6:1400 ip prefix-list PL_G----_PREFIXES description G---- _PREFIXES ip prefix-list PL_G----_PREFIXES seq 5 permit xxx.xxx.xxx.xxx.0/20 le 32 ip prefix-list PL_G----_PREFIXES seq 10 permit yyy.yyy.yyy.yyy/21 le 32 #sh ip prefix-list PL_G----_PREFIXES seq 5 seq 5 permit xxx.xxx.xxx.xxx.0/20 le 32 (hit count: 4833, refcount: 1) #sh ip route xxx.xxx.xxx.xxx.0 255.255.240.0 Routing entry for xxx.xxx.xxx.xxx.0/20, supernet Known via "static", distance 1, metric 0 (connected) Redistributing via bgp 1***6, ospf 100 Advertised by bgp 1***6 route-map G----_RANGES Routing Descriptor Blocks: * directly connected, via Null0 Route metric is 0, traffic share count is 1 #sh ip bgp xxx.xxx.xxx.xxx.0 255.255.240.0 BGP routing table entry for xxx.xxx.xxx.xxx.0/20, version 311740657 Paths: (1 available, best #1, table default) Advertised to update-groups: 544 552 555 591 Refresh Epoch 1 Local 0.0.0.0 from 0.0.0.0 (xxx.xxx.76.253) Origin IGP, metric 0, localpref 100, weight 32768, valid, sourced, local, best rx pathid: 0, tx pathid: 0x0 #sh ip bgp neighbors xxx.xxx.76.204 advertised-routes *> xxx.xxx.xxx.xxx.32/30 0.0.0.0 0 32768 ? *> xxx.xxx.xxx.xxx.40/30 0.0.0.0 0 32768 ? *> xxx.xxx.xxx.xxx.72/29 xxx.xxx.xxx.xxx.90 0 32768 ? *> xxx.xxx.xxx.xxx.88/30 0.0.0.0 0 32768 ? *> xxx.xxx.xxx.xxx.100/30 0.0.0.0 0 32768 ?
