Hi All, RFC7432, section 8.5, talks about DF election algorithm (service carving algorithm)
only for <ES, VLAN> for VLAN-based service or <ES, VLAN bundle> for VLAN-(aware) bundle service. But there wont be any vlan id for untagged interface and so I wonder how the service carving algorithm can be applied to elect the DF. Also, should I use the lower VLAN ID even in the case of VLAN-bundle service, for electing the DF? Could some one help me to understand this please? ==========<snip from RFC 7432, section 8.5>=============== 8.5<https://tools.ietf.org/html/rfc7432#section-8.5>. Designated Forwarder Election .... The default procedure for DF election at the granularity of <ES, VLAN> for VLAN-based service or <ES, VLAN bundle> for VLAN-(aware) bundle service is referred to as "service carving". .... Assuming a redundancy group of N PE nodes, for VLAN-based service, the PE with ordinal i is the DF for an <ES, VLAN V> when (V mod N) = i. In the case of VLAN-(aware) bundle service, then the numerically lowest VLAN value in that bundle on that ES MUST be used in the modulo function. .... =========<snip end>====================================== Thanks & Regards Jaikumar S
