[OSPF] RE: RFC3630 - Local and Remote Interface IP address

["Pandian, Vijay" <Vijay.Pandian at sycamorenet.com>]

Hi Dimitri,

Section 2.4.2 of rfc3630 says: "The Link TLV describes a single link."

Section 2.5.3 of rfc3630 says: "The Local Interface IP Address sub-TLV
specifies the IP address(es) of the interface corresponding to this link."

Section 2.5.4 of rfc3630 says: "The Remote Interface IP Address sub-TLV
specifies the IP address(es) of the neighbor's interface corresponding to
this link."

Doesn't this mean the Local and Remote Interface IP Address sub-TLV
corresponds to just ONE TE-Link?

There is no mention of "components" anywhere in this document. Even in
rfc4201, it is not clear that when multiple (component) TE-Links are
aggregated as a single numbered bundled link, there can be more than one
Interface IP address used for Local and Remote Interface IP Address.

Could you please provide a reference where this is clarified as the mean for
advertising multiple components at once. 

Thanks and best regards,

Vijay

hi vijay - this was meant for advertizing multiple components at once

        Subject:        RFC3630 - Local and Remote Interface IP address


Section 2.5.3 indicates that there can be more than one Local Interface IP 
address assigned to a (numbered) TE-Link. Similarly, section 2.5.4 
indicates that there can be more than one Remote Interface IP Address 
assigned to a (numbered) TE-Link.
 
Is there any requirement that the number of Local Interface IP address 
assigned to a given TE-link match the number of Remote Interface IP 
address.
 
Specifically, can a TE-Link have just one Local Interface IP address but 
multiple Remote Interface IP Address or vice-versa?
 
Best regards,
 
Vijay
