Hi Gyan,

Thanks for your support and comments on the draft.

The proposed encoding for L2 Bundle members and their attributes in OSPF is different than the ISIS encodings in RFC8668. ISIS encodings have “tighter” LSP space considerations that OSPF. The authors have proposed a simpler encoding scheme for OSPF – feedback/inputs are welcome.

The list of attributes in Figure 2 and 3 also includes L2 Bundle member Adj SID. Since the encoding scheme is similar to Layer 3 attributes, we can re-use the same sub-TLVs.

Thanks,
Ketan

I support WG adoption of this draft.

I agree that OSPF needs the functionality equivalent to that defined for IS-IS in RFC 8668.

I think the draft should include similar to RFC 8668 section 3 parallel layer 3 adjacencies 3 similar Sub TLVs mentioned flag for multiple parallel adjacencies.

Also maybe section 4 of RFC 8668 would apply as well to ospf advertisement of L2 bundle Adj sid.

Thanks

Gyan
