Hi everyone, in my company we are now deploying MRA, but I have some problems configuring the two expressway. In particular i get what you see in the attachments.
Can anyone help? Zones, search rules and domains are properly configured i guess.
Thanks a lot.

I would prefer going with dual NIC.
Example configuration
Expressway C
NIC IP 192.168.10.10 >> VOIP VLAN
Internal DNS Records
Certificate
CUCM
CUCM IP : 192.168.10.9
Certificate
Internal DNS Records
_cisco-uds._tcp.internal.domain.it SRV service location:
priority = 6
weight = 30
port = 8443
svr hostname =cucm.internal.domain.it
Do the same with other nodes.
Expressway E
NIC 1 IP 192.168.10.10 >> VOIP VLAN
NIC 2 IP 192.168.20.10 >>DMZ IP
Public IP 45.45.45.26
Internal DNS
Certificate
Public DNS Records
when configure dual NIC, use your network design. and the above is just an example configuration.

whats the status of the Zone between E and C is it active ?

The state is in Warning, can you check why it shows warning. its should show active.

The problem is exactly the one you mentioned. The status should be active, but instead it shows warning with reason "Systems unreachable" and I don't know why.

Is it a single NIC or dual NIC.
Looks like you have issue with SIP reachability . you need to check your configuration.

Hi there,
This document will have you covered. Have a look at the "Install MRA" section:

Can you also check or share the screenshot from Configuration >> Unified Communication >> Unified CM.
select the call manager and perform and refresh and see if it doesnt give any error?

The error message says that there is no Unified Communication traversal zone between the E and C. Correct that and check again.
01-22-2021 05:03 AM
yes I read it, but still... zones are configured. You can check the screenshot I already uploaded for more details.
01-22-2021 05:08 AM
The screen shots show a zone, but not that it’s a Unified Communication traversal zone. Please provide a screenshot of the entire configuration of the zone on both C and E.

Just a question.. on the version X12.5 the zones between exp-c and exp-e must be a Unified Communication traversal or Traversal Client - Traversal Server?

From what I know for MRA it always have to be the Unified Communication traversal specific type of zone.
