I have 2 Internet Connection with my client and one cisco router with 2 gis ports.My client has one cheap priced Internet connection and one heavy priced Internet connection.My client has some special demand:-
All Traffic should go cheap priced Internet connection with the help of router initialy and In case of Congestion in Network, heavy priced Internet should be used for time being till traffic load goes down.
Default gateway points towards the cheap internet connection, and IP SLA to track if the cheap internet is down, when it's down to use the expensive internet connection, and once the cheap internet connection is UP, it will automatically switch back to it.
We have one cisco router with 2 gigabitethernet ports and Links are comming through VSATs.I need to configure router for those VSAT links.All traffic should go first VSAT link initially.But the second link should be used in case of congestion in first VSAT link( traffic crosses treshold value) and also comes back all traffic in first VSAT link in case of traffic load goes down.Is it possible to fix treshold limit of traffic?
So, if don't mind, I'll ask my question, in your discussion
I have two ISP connection to my router, r1 it's a router which do NAT for both ISP's, here the schema
ASA5520 (2 for failover, it's acting like central point of VPN tunneling) int f0(172.16.1.3)-----connected---->r1(it's making NAT for my ASA5520, and connected to 2 ISP's, if one ISP goes down, it's switch to second, and when first ISP come up again, it's back to him), here is my config fo r1 router, and my question is: Why when I do clear ip nat translation *, several times...it's always diferent my router reboot with BUS ERROR, I'm Already change IOS, change routers, same thing on 28xx 17xx 37xx, why it's happends?
