Hello Cisco Networkers..
I have a pretty cool question.
I am by far not considered a expert in BGP but here is the question.
If you have a eBGP relationship between 2 ISP providers, both peers in the relationship should pass the FIRST (FULL INTERNET ROUTING SWITCHING TABLE) is this correct? I think so!
So, if they pass the FIRST (FULL INTERNET ROUTING SWITCHING TABLE) is the 0.0.0.0 included???
The reason is because that I see from the "show ip bgp neighbor x.x.x.x received-routes" command that they are passing me the 0.0.0.0 route as well as the FIRST Table...
If I have the FIRST table I should need the default, is this correct..
Please let me know if the 0.0.0.0 should be passed or not between to ISP's..
Your Query is correct if u have a single ISP active currently then you don't need any default route injected in your network as you already have the Full routing table.And this default route may cause your AS to be a transit AS for other destination via the ISP.so better is to block the default route injection.
