I try to create a Vlan that route traffic through multiple Cisco Devices. For that I create a vlan13 on each device and setup a IP on the ISR and the Device attached to the Nexus also have a IP on the same subnet.
The setup is like this:
ISR 4451:
interface Vlan13
description pfsense subnet
ip address 10.1.1.49 255.255.255.240
end
interface Ethernet-Internal1/0/0
description Trunk to internal switch module
switchport trunk allowed vlan 1,11,13
switchport mode trunk
end
SM-X
interface Vlan13
ip address 10.1.1.51 255.255.255.240
end
interface GigabitEthernet0/2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,13
switchport mode trunk
end
interface GigabitEthernet0/52
switchport trunk encapsulation dot1q
switchport mode trunk
switchport protected
end
Nexus 3000
vlan 1,13
interface Ethernet1/16
switchport access vlan 13
interface Ethernet1/47
I try to add switchport trunk encapsulation dot1q
to the nexus config but the command is unavailable. Maybe this is the issue of my config. The Server attached to the Eth1/16 Port is configured with IP 10.1.1.50/28 and the IP 10.1.1.49 or 10.1.1.51 is not accessible from that server.
switchport mode trunk
on Nexus Ethernet1/47. The encapsulation command is not needed as the Nexus always encapsulates. – user36472 Jan 19 '18 at 7:26
