Hello all,

I am confused by large community defined in draft-ietf-idr-large-community, wide community defined in draft-ietf-idr-wide-bgp-communities, extended community defined in RFC4360, community defined in RFC1997. Why do we need so many kinds of BGP communities? Can the large community be encoded in type 3 wide community? Thank you for your explaination.

Best Regards,
