Two sites, two switches, and issue setting up RIP

[Stephen_Stormon]

We have two sites with two Summit switches at each. We had a MPLS connection between the two sites and have since added a direct point to point (P2P) connection between the two locations. What we want to do it to configure the network so that all traffic between these sites will default to using the P2P connection and fail over to the MPLS is necessary. We don't believe our license allows for the use of OSPF, so we decided to attempt to implement RIP. We configured RIP to only export "direct routes". Things seem to be going well, but there is a route in each site that for some reason will not become the default and we don't know why:

Related routes at one end (172.22.16.5 is the MPLS router at the site and 172.19.1.1 is the P2P address at the far end of the P2P)
Ori Destination Gateway Mtr Flags VLAN Duration
#s 172.22.62.0/20 172.22.16.5 2 UG---S-um--f- Internal_Appliances 0d:0h:40m:13s
r 172.22.62.0/20 172.19.1.1 2 UG-D---um---- P2P_Express 0d:1h:56m:37s
#s 201.133.58.0/24 172.22.16.5 1 UG---S-um--f- Internal_Appliances 0d:2h:3m:4s
#r 201.133.58.64/26 172.19.1.1 2 UG-D---um--f- P2P_Express 0d:1h:56m:37s

Related routes at the other end (172.22.62.3 is the MPLS router at the site and 172.19.1.14 is the P2P address at the far end of the P2P):
Ori Destination Gateway Mtr Flags VLAN Duration
#s 144.202.234.0/24 172.22.62.3 1 UG---S-um--f- Default 775d:17h:39m:55s
#r 144.202.234.128/25 172.19.1.14 2 UG-D---um--f- P2P_Express 0d:2h:9m:37s
#s 172.22.16.0/20 172.22.62.3 1 UG---S-um--f- Default 0d:1h:55m:38s
r 172.22.16.0/20 172.19.1.14 2 UG-D---um---- P2P_Express 0d:2h:9m:38s
Why is it that the one route acquired by rip became the "Preferred unicast and multicast route" but the other one did not? Is the issue because there is already a statically defined route for that network and static routes take precedence over RIP imported routes?

[Stephen_Stormon]

So I guess there is no way to do what we want (without changing settings that aren't recommended to be changed) unless we change our static routes to point to the other end of the dedicated P2P line and then let the router create RIP routes for the MPLS connection?

Stephen,

I'm sorry. I made a mistake. I can only say in my defense that today is Monday...

Your problem is the PRIORITY of the route origin and that is not solved by changing costs.

Each route origin has a certain relative priority.

Static has a higher priority than RIP so a static route will ALWAYS be preferred over RIP routes, no matter the cost.

The command to change the PRIORITY of route origin is:
configure iproute {ipv4} priority [blackhole | bootp | ebgp | ibgp | icmp | isis | isis-level-1 | isis-level-1-external | isis-level-2 | isis-level-2-external | mpls | ospf-as-external | ospf-extern1 | ospf-extern2 | ospf-inter | ospf-intra | rip | static] priority {vr vrname}
However,THIS IS NOT RECOMMENDED. The documentation says:

Although these priorities can be changed, do not attempt any manipulation unless you are expertly familiar with the possible consequences. If you change the route priority, you must save the configuration and reboot the system.
Note
The priority for a blackhole route cannot overlap with the priority of any other route origin.

Can you post the whole routing table, including direct interfaces?
