Dear All, Does anybody had to migrate a entire BGP transit AS# from Cisco IOS to IOS-XR ? Our main concern is BGP, especially conversion from route-map, communities, conditional advertisement, template, peer-group up to RPL. Cisco offer a doc how to migrate from IOS to XR of about 40pages, but it's quite old (XR 3.2) and not so interesting. There are also a lot of documentation about XR/RPL, but I was not able to find a good doc about RPL, and how to translate complex IOS config to XR. Any experience on BGP best pratice with XR, af-group, session-group, neighbor-group, communities implementation from existing IOS config ? And how to you manage RPL editing? I mean with IOS you have some completion on TAB keystroke, but as RPL has to be edited within a text editor, you loose this kind of 'help'. Maybe we have to re-think our config from scrash :-). Thank in advance, Best regards, Marcel
