Routing

Hello Experts

 

Can any one guide me how to define the BGP community with 4-byte AS number. It would be the same format as below:

 

AS:NUMBER

 

like 123456789:110

 

Thanks

I kindly suggest you to look at the documentation.

Have you tried doing a search for Juniper articles relating to your question? Or taking the JIR - Junos Intermediate Routing which will help you learn a lot plus give you lab exercises? For example i just did a search from your quesion and this was the first Juniper article

Seems like you have a good case to get a Juniper consultant to help you deploy the product.

Hello

 

I know JUNOS very well. What I am asking here is not basic stuff !! My AS is public with 4 bytes and I want to advertise IPV4/IPV6 pool to one of our partner with community tag. Partner is using 2 byte AS number. BGP neibhourship is up and running.

 

With 2 bytes AS number, community definition is very easy and very common. BGP extended communities are used normally for MPLS VPN services (target, origin etc)

 

I did not find single example for Juniper to use BGP extended community for 4 byte as number other than in MPLS services. Thats why I asked question here !

lyndidon gave you the answer:

If you take the time to experience yourself, you will see that it works and is supported in extended communities like route targets, but that notation is not supported for standard communities (at least yet).

Again, We are providing you with links that will explain the questions the ask. On the very link posted, if you look at the links to the side, here is one:

http://www.juniper.net/techpubs/en_US/junos12.2/topics/concept/4-byte-as-numbers-path.html

 

If you read it and then say, it does not apply and here is why, we can go on from there.

guys

Extended communitues can do it but not standard ..
