[c-nsp] GRE and MSS adjust on ASR9K

[Sarala Akella (sakella)]

Hello John,



Router using  "ip tcp adjust-mss <mtu>



On ASR 9k

RP/0/0/CPU0:router(config)#tcp mss  <mtu>

are different commands (tcp mss will only impact the locally

originated TCP sessions, not the sessions flowing through the router)



In case of further questions please open a PDI case

Best regards,

-Sarala

Thanks! My Google-Fu must be weak. That page didn't turn up for me

despite multiple searches with variations of "IOS XR tcp mss" and

things like that. I appreciate the help.
