Tom, I have config'd my Lab and it works: Your router 9.9.9.9 is my rtrB: rtrB#sh ip bgp 100.0.0.0 BGP routing table entry for 100.0.0.0/24, version 2 Paths: (1 available, best #1) Advertised to non peer-group peers: 10.0.0.33 best, i - internal Origin codes: i - IGP, e - EGP, ? - incomplete

Below, you can see that he's learning 2 prefixes from both routers in AS 400. By looking at the ">" you can see which route he's putting in his routing table. This is based on the MEDS that rtrA (your 6.6.6.6) and rtrB (your 9.9.9.9) are sending him. See below: rtrC#sh ip bgp n 10.0.0.18 rou BGP table version is 16, local router ID is 10.0.0.17 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path *> 100.0.0.0/24 10.0.0.18 5 0 400 i * 100.0.1.0/24 10.0.0.18 10 0 400 i Total number of prefixes 2 rtrC#sh ip bgp n 10.0.0.34 rou BGP table version is 16, local router ID is 10.0.0.17 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path * 100.0.0.0/24 10.0.0.34 10 0 400 i *> 100.0.1.0/24 10.0.0.34 5 0 400 i Total number of prefixes 2 My configs are the same as yours with the exception of the route-map name. My route-map name matches the route map that I am calling in my nei statement to 10.0.0.33 on rtrB (9.9.9.9).

BGP question, why do I get "Not advertised to any [7:31528] BGP question, why do I get "Not advertised to any peer" Below is from an isolated lab configuration, appologies to the actual owners of any addresses of AS numbers used. I have two routers connected together via a serial line. They are in AS400. They are both connected to AS100 via another serial line. Both have a route map affecting advertisements to AS100. They each have an ethernet with a /24 on it. The /24 is getting into BGP via a network command. The two routers have the loopbacks 6.6.6.6 and 9.9.9.9 network 100.0.0.0 /24 is connected to the ethernet of router 6.6.6.6 network 100.0.1.0 /24 is connected to the ethernet of router 9.9.9.9 When I am on router 6.6.6.6 and I look at the advertisement of network 100.0.1.0 /24 is looks fine When i am on router 9.9.9.9 and I look at the advertisement of network 100.0.0.0 /24 it says "Not advertised to any peer" Any ideas why the difference???? Why can't 100.0.0.0 be avertised to any peer? Both routers have been rebooted. The configs look almost identical. router_6666#sho ip bgp 100.0.1.0 BGP routing table entry for 100.0.1.0/24, version 2 Paths: (1 available, best #1, table Default-IP-Routing-Table) Advertised to non peer-group peers: <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 10.0.0.17 Local 10.0.0.38 from 10.0.0.38 (9.9.9.9) Origin IGP, metric 0, localpref 100, valid, internal, best router_9999#show ip bgp 100.0.0.0 BGP routing table entry for 100.0.0.0/24, version 9 Paths: (1 available, best #1, table Default-IP-Routing-Table) Not advertised to any peer <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Local 10.0.0.37 from 10.0.0.37 (6.6.6.6) Origin IGP, metric 0, localpref 100, valid, internal, best router 6666 interface Loopback0 ip address 6.6.6.6 255.255.255.255 ! interface Ethernet0 ip address 100.0.0.1 255.255.255.0 ! interface Serial0 ip address 10.0.0.18 255.255.255.252 ! interface Serial1 ip address 10.0.0.37 255.255.255.252 ! router bgp 400 no synchronization bgp log-neighbor-changes network 100.0.0.0 mask 255.255.255.0 neighbor 10.0.0.17 remote-as 100 neighbor 10.0.0.17 route-map set_meds out neighbor 10.0.0.38 remote-as 400 no auto-summary ! ip classless ip route 9.9.9.9 255.255.255.255 10.0.0.38 no ip http server ! access-list 20 permit 100.0.0.0 access-list 21 permit 100.0.1.0 route-map set_meds permit 10 match ip address 20 set metric 5 ! route-map set_meds permit 20 match ip address 21 set metric 10 Router 9999 ! interface Loopback0 ip address 9.9.9.9 255.255.255.255 ! interface Ethernet0 ip address 100.0.1.1 255.255.255.0 ! interface Ethernet1 no ip address ! interface Serial0 ip address 10.0.0.38 255.255.255.252 no fair-queue clockrate 2000000 ! interface Serial1 ip address 10.0.0.34 255.255.255.252 clockrate 2000000 ! router bgp 400 no synchronization bgp log-neighbor-changes network 100.0.1.0 mask 255.255.255.0 neighbor 10.0.0.33 remote-as 100 neighbor 10.0.0.33 route-map set_meds out neighbor 10.0.0.37 remote-as 400 no auto-summary ! ip classless ip route 6.6.6.6 255.255.255.255 10.0.0.37 no ip http server ! access-list 20 permit 100.0.0.0 access-list 21 permit 100.0.1.0 route-map set_med permit 10 match ip address 21 set metric 5 ! route-map set_med permit 20 match ip address 20 set metric 10 Tom Pruneau Technical Trainer Network Operations GENUITY 225 Presidential Way Woburn Ma. 01888 --------------------------------------------------------------------------- This email is composed of 82% post consumer recycled data bits --------------------------------------------------------------------------- "Once in a while you get shown the light in the strangest of places if you look at it right" Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=31571&t=31571 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
