MX65 connecting to ASR1000

[auhyden]

From what I have seen in documentation for installing the MX65, it says to connect it up to a switch.

Has anyone connected a MX65 to a router?

We have a crash kit with a MX65 and Starlink.

Connection flow is:
Starlink <WAN_PORT> MX65 <LAN_PORT_3> ASR >> Internal LAN

My customer is doing this. We assigned a /30 point-to-point connection, and we are unable to ping the router from the Meraki. 

We configured this on the router:

interface GigabitEthernet0/0/0
ip address 20.176.255.18 255.255.255.252
no ip redirects
no ip proxy-arp
ip nbar protocol-discovery
ip pim sparse-mode
ip nat outside
ip ospf network point-to-point
no shutdown
negotiation auto
cdp enable
ip virtual-reassembly

router ospf 100
no passive-interface GigabitEthernet0/0/0
network 20.176.255.16 0.0.0.3 area 0.0.0.168

On the MX65 we created a dummy vlan 801 and assigned the /30 Router_P2P

We also read something that said this:
On your MX create a new VLAN. Assign it a random subnet your not using. Put three LAN ports on the MX84 into that VLAN in access mode. Plug your MX WAN interface into one of these MX84 LAN ports. Plug your router and Internet circuit into the other two ports.

That seemed weird.

Does anyone have insight to this?

Not going to lie, that's a weird setup having an MX65 in front of an ASR1K.

That said, there's no reason it shouldn't work.

Looking purely at the LAN side, what you've written above should be fine provided the MX65 LAN port connecting to the ASR is configured as an access port with VLAN 801.

A little. It's an emergency kit being deployed to support a Site-to-Site VPN solution.

I was thinking the same. Our Primary objective is to get that Starlink working so the MX can register to the Cloud. Then I can worry about the LAN portion. I think you're right though. The issue would be with how the LAN port from the MX65 is configured going to the ASR. 

I'll check that out and update then!
