‎05-30-2020 08:52 PM

Hi all,

 

May i know whether someone can sharing the book/blog/url that referring how to integrate Segment Routing with RSVP-TE? Currently in "Day One" book just have Segment Routing with LDP only. So i'm try to learn how Segment Routing will integrate with existing RSVP-TE.

 

Thanks and appreciate any help.

Hello,

AFAIK, there is no comprehensive one-and-done book/article/url that encompassess all aspects of RSVP-TE and SR integration.

That being said, the best recommendation at this time is to run SR and RSVP-TE in parallel, "ships-in-the-night" approach.

There is even a RFC about it https://tools.ietf.org/html/rfc8426 

That being said, there are multiple other techniques to carry SR over RSVP-TE if You so desire:

1/ RSVP Pop-n-go https://forums.juniper.net/t5/Industry-Solutions-and-Trends/RSVP-TE-Pop-amp-Go-Using-a-shared-MPLS-f...

(additional links are at the bottom of the above page)

2/ SR over ISIS Forwarding adjacencies https://www.juniper.net/documentation/en_US/junos/topics/concept/segment-routing-rsvp-fa.html

3/ IGP shortcuts for SR ("traffic-engineering shortcuts family inet-mpls", see Day1 book "Inside Segment Routing" pages 46-47)

HTH

Thx

Alex

Hi arrseniv,

 

 

Thanks for the url. I found other good url https://www.sanog.org/resources/sanog34/SANOG34-Tutorials-spring-for-service-providers-v1.3.pdf   but not so clear regarding integrate with legacy network that use RSVP-TE. I mean what need to be configure on legacy network. For example if SR integrate with LDP then just use stiching and Mapping Server and Mapping Client.

 

But how if need integrate with RSVP/RSVP-TE. Hopefully Juniper can do good doc for this.

 

Thanks

Hi,

 

Maybe the Day One Book "Inside Segment Routing" could help... pages 49 to 52.

You can get the book in the link: https://www.juniper.net/documentation/jnbooks/en_US/day-one-books/
