Hi Authors,
Came across following in (draft-ietf-lisp-rfc6833bis-24) ,
Page 14, under EID Prefix:
"When a Map-Request is sent by an ITR because a data
packet is received for a destination where there is no mapping
entry, the EID-Prefix is set to the destination IP address of the
data packet, and the 'EID mask-len' is set to 32 or 128 for IPv4
or IPv6, respectively. When an xTR wants to query a site about
the status of a mapping it already has cached, the EID-Prefix used
in the Map-Request has the same mask-length as the EID-Prefix
returned from the site when it sent a Map-Reply message."
Page 15, under EID-to-RLOC UDP Map-Request Message:
"A Map-Request is sent from an ITR when it needs a mapping for an EID,
wants to test an RLOC for reachability, or wants to refresh a mapping
before TTL expiration. For the initial case, the destination IP
address used for the Map-Request is the data packet's destination
address (i.e., the destination EID) that had a mapping cache lookup
failure. For the latter two cases, the destination IP address used
for the Map-Request is one of the RLOC addresses from the Locator-Set
of the Map-Cache entry. The source address is either an IPv4 or IPv6
RLOC address, depending on whether the Map-Request is using an IPv4
or IPv6 header, respectively."
Isn't second case above referring to map-cache refresh for EID Prefix and
"Destination IP address" as EID Prefix (instead of RLOC)?
Typo or I am missing something?
Thanks,
Prakash
