Hi Sue,

 

Please use RFC3443 as the normative for TTL behavior. 

 

Cheers,

Jeff

Greetings: 

 

The I2RS WG would like some advice. 

 

Is there ever a case when doing label swap you would ever want to decrease the TTL at the same time?  Our initial I2RS RIB (draft-ietf-i2rs-rib-data-model-10) had added this 3 years ago due to comments.  However, we are question now whether this is valid. 

 

We have asked the mpls wg, i2rs wg, and rtgwg wg – to see if anyone knows if this is a useful feature. 

 

Thank you, Susan Hares 

Co-chair I2RS WG
