[e-nsp] Problem with MST cisco and extreme switches

[Ramón Alvarez Rayo]

Hello,

 

I am closing a fibre ring with 2 extreme summit 48si/Full L3 and a cisco
2960, i´m tryng to connect using MSTP but I can´t see any packets between
extreme switches and catalyst switch, this is the configuration:

 

NODO 2

 

configure vlan "BACKBONE" tag 500     # VLAN-ID=0x1f4  Global Tag 3

configure stpd ALFA1 add vlan "BACKBONE"

configure vlan "BACKBONE" ipaddress 10.240.0.2 255.255.255.224

configure vlan "BACKBONE" add port 49 tagged

configure vlan "BACKBONE" add port 50 tagged

 

enable stpd ALFA1 rapid-root-failover

configure stpd ALFA1 tag 500

configure stpd ALFA1 mode dot1w

configure stpd ALFA1 port link-type point-to-point 49

configure stpd ALFA1 port link-type point-to-point 50

enable stpd ALFA1

 

NODO 3

 

configure vlan "BACKBONE" tag 500     # VLAN-ID=0x1f4  Global Tag 3

configure stpd ALFA1 add vlan "BACKBONE"

configure vlan "BACKBONE" ipaddress 10.240.0.3 255.255.255.224

configure vlan "BACKBONE" add port 49 tagged

configure vlan "BACKBONE" add port 50 tagged

 

enable stpd ALFA1 rapid-root-failover

configure stpd ALFA1 tag 500

configure stpd ALFA1 mode dot1w

configure stpd ALFA1 port link-type point-to-point 49

configure stpd ALFA1 port link-type point-to-point 50

enable stpd ALFA1

 

On cisco switch this is the configuration:
