draft-hegde-rtgwg-virtual-multi-instance-00

This is the IPR I was referring to:
http://www.google.com/patents/US20140010117


I’m know there is other IPR in this area but this one is very similar with
the virtual instance in that it isolates the remotes sites and handles
back-door links w/o any update to the remote routers.

Thanks,
Acee

draft-kumar-sfc-nsh-udp-transport & draft-ietf-rtgwg-dt-encap

Hi all,

First of all, I like the idea of directly encapsulating NSH over UDP since it eliminates the unnecessary
VXLAN header encapsulation burden. However, there are still many headaches surrounding any UDP-based
encapsulation proposal such as congestion controll, IPv6/UDP checksum, MTU and fragmentation, UDP
dest port resource utilization. 

Since UDP has been selected as a tunnelling technology by more and more encapsulation proposals besides
NSH-in-UDP, including but not limited to VXLAN, VXLAN-GPE, MPLS-in-UDP, IP-in-UDP,  TRILL-in-UDP,
draft-ietf-rtgwg-dt-encap would be more useful in practice if it could give us concrete
recommendations regarding the above headaches surrounding the UDP tunnelling usage, IMHO.

Best regards,
Xiaohu

Comments on draft-shaikh-rtgwg-policy-model

Hi,

 

As pointed this morning during the WG session :

-          We need to clarify (asap if possible) the boundary between this policy model and what should be defined in protocol models to extend the policy. In the current version, it looks like a mix of having part of IGP defined in the generic policy framework and so expecting some other extensions in IGP models. For BGP, all is within BGP. My proposal would be to let all the protocol extensions to be in protocol models, this includes :

o   Protocol specific matching

o   Protocol specific actions

o   Install-protocol identity for that protocol => so need to remove the existing ones for ISIS, OSPF, BGP in the current version.

-          Regarding tags, as pointed today, I would like to have “tag” to be a generic local identifier rather than pointing only to IS-IS and OSPF. Any route within a RIB may have a local tag (this local tag can be learned from the routing protocol or set by configuration or policy). So setting a tag does not refer to any igp-action.

-          Also regarding the “igp-action” container, I’m not in favor of having separate containers for igp-actions, bgp-actions and generic-actions. Two possibilities :

o   Each protocol creates a container (e.g. isis-actions, ospf-actions …) which augments the action container. Isis-actions and ospf-actions may be different (for example in setting route-type or metric type …)

o   Just having the “actions” container and put all the actions here whatever the applicable protocol.

o   Similar approach to be taken for protocol specific conditions

-          I would be in favor in adding routing table matching condition and a way to select also a destination routing table. E.g. , I use an import policy to force a routing protocol to insert routes in a specific routing table rather than the default one. Or I want to authorize routes from multiple routing tables to be exported to a particular protocol.

Python implementation of MRT lowpoint algorithm

All,
 
We wrote a Python implementation of the MRT lowpoint algorithm following the pseudo-code in the draft, and have included it in the text of draft-ietf-rtgwg-mrt-frr-algorithm-05. 
 
The code is also posted on github at:
 
At this point, the Python implementation is included in the draft as additional information, with the pseudo-code text representing the normative version of the algorithm.  For the next revision of the draft, I think it makes sense to make the Python implementation the normative version of the algorithm since it can actually be run to produce a definitive result for any input topology.  However, I want to elicit feedback from the WG as to whether or not it makes sense to do this.
 
We can also discuss this point at the RTGWG session on Wednesday where I will give an update on the MRT-related drafts.
 
Thanks,
Chris

Fwd: New Version Notification for draft-lamparter-rtgwg-dst-src-routing-01.txt

Hi rtgwg,

addressing some of the feedback from IETF 91 (Hawai'i), I've posted -01
of the dst-src-routing draft.

The major change from -00 consists of the removal of all references to
the "extra qualifier" stuff.  (That was suggesting a registry to put new
route qualifiers into, flowlabel being one of the candidates.)

As it is now, the draft simply explains SADR for a non-homenet-savvy
implementor of a routing system.  It also looks at contact areas between
SADR and other parts of the routing system, in particular its
interaction with recursive route resolution is an open question.

This functionality is used in homenet but is rather out of scope there
since it changes the way basic routing works.  Therefore, I'd like to
get this adopted as WG document in rtgwg.  I'm hoping that homenet's
decision to depend on this provides sufficient argument on the
"interest"/"need" front of things.

Feedback of course very welcome,

-David

Abstract:
   This note specifies using packets' source addresses in route lookups
   as additional qualifier to be used in route lookup.  This applies to
   IPv6 [RFC2460] in general with specific considerations for routing
   protocol left for separate documents.

It had to be manually posted, which is perhaps why there wasn't an 
automatic email sent to the list.
