[cisco-voip] Expressway Cluster failover for MRA

[Gerence Guan]

Hi Everyone.

I was googling the answer for MRA failover and found this maillist.
Got a similar setup as Jonathan's environment.
Having a pair of expressway C&E in primary DC, and planning to setup
another pair of expressway C&E in the DR site. All MRA should go via
primary DC, only use DR site when primary is down.

Can I achieve this with different priorities in SRV? Anyone tested  or make
it working?

Best Regards,
Guan
