Routing with two ISP's

Michael Durham

Level 4

I have two ISP's.  One Verizon 4G and the other is HughesNet.  Can I route ONLY my GRE tunnel out the Verizon IPS and everythingelse out HughesNet withthe equipment I have now?

I tried setting this up using sub-interfaces on my router just to start but the PC could not get any Internet connectivity.  I may have needed to do a reload on the router as I had to do to get it working when I put the satellite back directly connected.  Sometimes these routers seem to get routing confused. The Verizon is on Vlan 30 and the Sat is on Vlan 31 with a trunk to the router.  Its too late to try again tonight.

I have a GRE Tunnel going back to my corp office of the IP phone above and when I have just one ISP connected to the router and I o not use sub-interfaces, everthingworks perfect! Well, if I use Verizon 4G that is.  When I use the HughesNet, everything works this way except VoIP call suck dueto the 700ms ping times.  So my goal is to have my GRE tunnel for the IP phone go out Verizon while all other Internet traffic goes viathe satellite.

I need to do this for several reasons.

1. VoIP over the satellite does not work (we've done our best to make it work)

2. The Verizon 4G is my cell phone and when I leave home I take it with me thuis killing internet at home.

3. If I use the cell phone for both VoIP and Internet surfing/downloading, the battery drain is so bad that the phone dies in 4-6 hours.

4. I need to make calls with the VoIP phone becasue the customers get that caller ID otherwise the get my home phone. (not cool).

I could use your help please.

I am running into this problem when I change the tunnel from gi0/0.30 to gi0/0.31:

May 30 2013 18:06:10.511: %CRYPTO-4-IKMP_NO_SA: IKE message from 55.9.6.90 has no SA and is not an initialization offer

I have tried to use clear crypto session, clear crypto isakmp but the problem persists.  I haver to delete the tunnel and recreate it to fix the problem and I know that should not be the answer.

Any suggestions?

I found the answer to the above question:

clear crypto sa

Porblem solved.  I am gonna have to add that to the EEM command set too.
