again the question why i do have to ? i can perfectly fit in single-digit as well as a few dozens of colors in a single RI LSA - what is your concern - except that we may use inappropriate large space for TE ? any reasonable implementation SHOULD restrict the node color set, such that overwhelming the 64K of RI LSPs is not going to happen. | > the 'per-link' admin-groups serve as a good example here: | > initially conceived as "you won't ever need more than 32" we have | > now arrived at a variable length (unbounded) extension. | > | > http://tools.ietf.org/html/draft-osborne-mpls-extended-admin-groups-00 | > | > for a humorous take to it, have a look at | > http://tools.ietf.org/html/rfc1925 | > rule (9) and (10) | > | > /hannes | > | > On Oct 21, 2013, at 3:12 PM, Acee Lindem wrote: | > | >> Hi Shraddha, | >> Since the size of the tag data is unbounded, could you either put it in a separate OSPFv2 opaque LSA and OSPFv3 LSA or limit the size to some maximum number of tags, e.g., 16? | >> Thanks, | >> Acee | >> On Oct 21, 2013, at 7:05 AM, Shraddha Hegde wrote: | >> | >>> Hi All, | >>> | >>> We have posted a draft on " Advertising per-node administrative tags in OSPF" and would like to hear your views on it.
