Troubleshooting with IOS BGP and IOS XR BGP - routing table Empty

[saul.reyes]

Hi

actually we tried to make a neigborhood between ASR9000 and Cisco 7600, we have the neigborhood active but on routing tables from ASR only have the networks locals or connected doesn´t learn anything from BGP 7600

the diagram is this:

When try to know the routes on ASR9000 from Cisco 7609 happen the follow

the neighbor is UP from Cisco 7600 and ASR 9000 but the routing table is empty.

the config on cisco 7600 is:

router bgp 2006

neighbor 172.16.14.6 remote-as 64512

address-family ipv4

neighbor 172.16.14.6 activate

the config on cisco ASR9000 is:

router bgp 64512

bgp router-id 172.16.161.1

address-family ipv4 unicast

!

neighbor 172.16.14.5

  remote-as 2006

  address-family ipv4 unicast

Help us

Best Regards

I am not seeing any network statements in the parts of the configuration that you have posted. Are there any network statements in the parts that you have not posted? If not then this would explain why BGP is not advertising any routes.

Another important one is the fact that in XR you need to have RPL policies (even if they only have a "pass-all" functionality) to accept inbound/outbound routes in eBGP.

Check the article on the asr9000 unequal cost multipath that has some sample BGP outputs and show command verifications that may help also.

If not the case, get us the XR config from the A9K side.

Also what does the bgp table on teh IOS side look like? as Richard suggests, there doesnt seem to be anything injected by the 7600 itself.

Thanks so much for your response

we put

route-policy pass-all

  pass

end-policy

and apply over neighbor and the BGP tables from 7600 beggining to operate
