BGP command: disable-peer-as-check

[croue]

Hi,

I have a question regarding the BGP command "disable-peer-as-check" on Nexus 7700.

I have a Datacenter architecture with Nexus 7700. From a VRF in AS BGP (65000), I need to go to the AS BGP (65500), to go to an other VRF, in AS BGP (65000): 65000 - 65500 - 65000

With the command "allow-as-in", it doesn't work.

With the command "disable-peer-as-check", it works. But does not this command create a network loop risk?

Is there an other solution?

Thanks for your help.

Have you tried with as-override or its synonym over NX-OS on the device(s) with AS 65500? (under the interfaces facing to routers with AS 65000)

Try allowas-in 10 - sometimes your AS-Path string contains too many local AS instances. (e.g. 2byte vs. 4byte AS# scenarios)
