What's the best practice for the MX IP and VLAN, Lets say that my Cisco Core VLAN 1 is set to 192.168.70.1
How should I set the MX
Name Default
Subnet: 192.168.70.0/24
MX IP: 192.168.70.254 (or Any Available IP)
VLAN ID 1 is ok to use same VLAN 1?
Cisco switch
interface GigabitEthernet1/0/36
description Uplink to FW
switchport trunk encapsulation dot1q
switchport trunk native vlan 1
switchport trunk allowed vlan 1,2 (I have a second vlan for testing)
switchport mode trunk
Hey TonyBoy,
With out knowing more about your topology I personally cant give you a 100% answer however I can tell you that as long and the MX and the 3750 have IP interfaces on the same vlan you will be able to route between them.
Side Note: using vlan 1 is against best practice in Cisco world but not necessarily in the Meraki world
Does the 3750 have other layer 3 VLANs configured on it?
Vlan 1 192.168.70.1 Default
Vlan 2 192.168.71.1 Wireless
Vlan 3 192.168.72.1 Cameras
Vlan 4 192.168.73.1 Voice
Vlan 5 User
Vlan 6 Production
Vlan 7 Firewall (ASA is living here)
Vlan 10 Servers
Cisco Core is using EIGRP
router eigrp 100
network 192.168.76.0
network 192.168.253.0
network 192.168.254.0
redistribute connected
passive-interface Vlan254
eigrp router-id 192.168.70.1
!
ip default-gateway 192.168.76.254
Is your MX meant to be your 3750's default gateway at 192.168.76.254 or is this another device?
will be the MX, the Core is already configured pointing at the FW
Hey Tony,
Is the goal to replace the ASA?
correct the MX will replace it and set it as the gateway
