VLAN trunking between Juniper EX -> Cisco Catalyst -> and Cisco Router
- by Hugo Garcia
I have the following scenario:
EX2200 Switch whit
ge-0/0/6 set as an access port on VLAN 80
ge-0/0/0 set as a trunk
port connected to a catalyst switch and various vlans allowed to pass includin vlan 80
On the Catalyst Switch.
port #3 set up as a trunk port that receives traffic from the EX switch.
port 46 is set up also as a trunk port that connects to a cisco router.
Port #48 is where the host used to be connected
host - EX2200 - Catalyst - Router
the problem is that this EX2200 is a new addition to the network and the host connected previosly to the catalyst switch.
traffic is not getting from the host to the router, but the router can send ARP request to the host.
following is the relevant configuration:
Catalyst Switch:
interface GigabitEthernet1/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 80,82,83,93,289
switchport mode trunk
mtu 1532
media-type rj45
speed 1000
duplex full
arp timeout 300
!
interface GigabitEthernet1/48
switchport access vlan 80
switchport mode access
mtu 1532
media-type rj45
speed 100
duplex full
arp timeout 300
no cdp enable
!
EX2200 Switch:
