This is more of a question about possible solutions to a problem that we experienced recently.
QUESTIONS:
-Are there any tools/protocols/setup/solutions/equipment/etc that would have helped my network to either automatically respond or more quickly respond to network latency on one of my Internet providers that one our clients uses for inbound connectivity to our location.
-Even if I had the most elaborate routing, multiple ISPs, tools, etc., do I still have no control over the inbound connection of my client in a BGP environment.
CONFIGURATION: Two Internet providers (1 Tier 1 and 1 Tier 2) setup with BGP on two
2600XM routers taking default routes (the routers are no longer able to handle full routes).-Outbound traffic is directed to the Tier 1 network. No outbound load balancing is done since we are just using default routes.
PROBLEM EXPERIENCED:
-Client A was experiencing latency of 200+ ms and was not able to use the application.
-troubleshooting was a bit confusing since I saw latency on both Internet providers but in the end it was just on the Tier 2 provider.
-It was determined that the tier 2 provider was experiencing latency on one of its edge routers but it did not go down.
-It was determined that client A was using the tier 2 provider for inbound connectivity which as far as I know can only be chosen by their provider. Is there is some other way????
-After about 2hr and 15 minutes, I decided to shut down the tier 2 provider to force all connectivity for inbound and outbound through the tier 1 provider. I only did this after confirming that our other client would not be affected and as a last resort. This does not seem to be the best way to go about resolving the issue.
-This brought up the client to acceptable latency.
This was considered a redundancy failure by the client and my company's management.
Your comments/help are appreciated.
