bgpd: add new draft for redirect ip for flowspec
that new option will overwrite simpson draft. There is a new ecommunity
option whose type is 0x1 and subtype is 0xc. That option is defined
here on iana.org/assignments/bgp-extended-communities page:
- bgp-extended-communities.xhtml#trans-ipv4
It contains the IP address to redirect traffic to. The understanding of
the draft is the following one:
- if that community is only present, then the ip contained inside will
be chosen as nexthop.
- if that community is provided along with simpson extended community,
then only the new redirect ip draft will be used. however, both will be
displayed.
- in other cases, if there is only the simpson extended community, then
the nexthop IP of the NLRI will be chosen.
