Hi all. Does anybody know how to establish RSVP path between Cisco and Extreme X460 XOS 15.6 switches?
When i tried this I have received errors on C7600:

It appears that the neighbor is sending ATM Label range in RESV message. So the local node will ignore and send error message. You may hvae to check why Extreme is sendng C-Type 2 instead of C-Type 1.

Hi, Nagendra
Thanks for your answer.
I've opened cases with Cisco and Extreme.
RSVP RESV message contains FLOWSPEC Object class=9 C-Type=2 as described in RFC2215
TOKEN_BUCKET_TSPEC parameter is a part of FLOWSPEC Object.
The XDR description of this parameter is:
struct {
float r;
float b;
float p;
unsigned m;
unsigned M;
} TOKEN_BUCKET_TSPEC;
where [p] means peak traffic rate.
Cisco doesn't accept zero p-value. Default Extreme p-value is zero.
It is possible to change it via Extreme profile configuration
configure mpls rsvp-te profile "rsvp_profile" bandwidth peak-rate *** Kbps
