Rajesh, Also you can change the service SID for a subset of prefixes using a policy, to apply a flex-algo for example, but you do not want to change the next-hop for each new service SID. Mustapha. From: spring On Behalf Of Rabadan, Jorge (Nokia - US/Mountain View) Sent: Monday, July 19,

Hi All, For best effort service, flex algo - Resolve SRv6 Service SID for forwarding. For SR-TE, CAR/CT - Resolve BGP next hop for forwarding. There is no unification here, it's better to unify. Any other solution is OK. Thanks Rajesh Juniper Business Use Only From: Rabadan, Jorge (Nokia -

I agree with Jorge.. In fact I find the tone of the comment to be very inappropriate: *> In case of best effort/flex algo we must mandate user to set corresponding locator as BGP nexthop for srv6 routes.* *No we MUST not mandate anything to the user. * *We MUST provide flexibility to address

Hi Rajesh, The draft is written so that the next-hop address MAY be covered by the locator, but there are cases in which the next-hop address is not part of the locator prefix, and there are implementations already allowing that, so I don’t agree the document should mandate what you are

2021-07-19 Thread Rajesh M
Hi All, As per this draft, this is how resolution must work. 1)For Non Intent service Route: if BGP next hop is not reachable return. Resolve SRv6 Service SID for forwarding. 2)For Intent service Route (IGP Flex-Algo first then BGP CAR then SR Policy): BGP next hop is not reachable return.

Re: [bess] Request discussion on Cumulative Link Bandwidth Draft

2021-07-19 Thread Vivek Venkatraman
The implementation of Link Bandwidth in FRR uses a transitive community to signal & perform an automatic accumulation at the AS boundary. This seems useful as it obviates the need for additional info (configuration) at each AS boundary to generate a new community using accumulated values.
