New ISP Circuit cutover - routing issues
I am in the process of switching over from one ISP circuit to another.
I have a /28 on an existing circuit I have a /29 and a /28 on the new circuit, I had the carrier route both the new /29 and /28 to the same gateway.
What I would like to do, is put the new circuit in along side the existing, so I can cut over connections one at a time to the new circuit.
For example:
Circuit A 207.67.1.1/28
207.67.1.2 Gateway
Circuit B 63.146.1.1/29
63.145.1.1/28
63.146.1.2 Gateway
I have two interfaces defined in the same zone (ZoneA).
207.67.1.3/28 from Circuit A
63.146.1.3/29 from Circuit B
I have an existing static route to Circuit A gateway
0/0 - 207.67.1.2 Distance 10, Priority 1 Interface1
I thought all I needed was another static route for Circuit B gateway (same distance, different priority)
0/0 - 63.146.1.2 Disttance 10 Priority 5 Interface2
I am testing with a VIP
I have the VIP and policy setup to NAT from ZoneA/Interface2(63.146.1.3) to an internal address
The routing monitor shows
Static 0/0 - 207.67.1.2 distance 10
Static 0/0 - 63.146.1.2 distance 10
Connected 207.67.1.1/28 - 0/0 Interface1 distance 0
Connected 63.146.1.1/29 - 0/0 Interface2 distance 0
Connected 63.146.1.1/29 - 0/0 Interface2 distance 0
Connected 63.146.1.1/29 - 0/0 Interface2 distance 0
Needless to say, I'm clearly missing something, or fundamentally just don't understand something.
The gateway 207.67.1.2 pings (ping enabled)
The gateway 63.146.1.2 pings (ping enabled)
The interface 63.146.1.3 does not (ping enabled)
Is seeing 63.146.1.1 in the routing table 3 times a clue.
Do I need some sort of policy route to drive the traffic
Or is this just stupid and completely wrong for what I am trying to accomplish
