Hi, all, I’ve prepared this review the request of Magnus Westerlund, who is preparing a TSVART review. My comments focus on the issue of fragmentation and tunneling. These are relatively minor issues that are simple to address, but not quite what I would consider nits. Joe ------ -- Regarding fragmentation: The doc does the right thing by not trying to describe a solution itself. However, it cites RFC 5565, which cites RFC4459. That's where the only trouble lies - 4459 is incorrect, as noted in draft-ietf-intarea-tunnels. I might suggest they continue to cite RFC 5565 but indicate that the requirements for tunneling are under current revision and cite draft-ietf-intarea-tunnel (at least informationally) too. It might also be important to discuss the challenge of tunnel configuration in a multicast environment, which is addressed as well in draft-ietf-intarea-tunnels. - other issues: 7.2 correctly notes that the TTL should be set per tunneling policy, but gives no advice as to how that is done (again, a pointer to draft-ietf-intarea-tunnels would be useful) ------
