I am currently working on a site that has two ISR2911 Routers. ROUTER A is connected to our MPLS provider via eBGP on a 10Meg Circuit and ROUTER B is connected to our MPLS provider via eBGP on a 50Meg Circuit. Both of these routers are connected to switches that allow for HSRP for the 3 VLANs at this site. A few days ago I noticed that this site was configured with ROUTER A as the "active router" in the pair and ROUTER B as the "standby router", so I went in and reversed this as ROUTER B has the bigger MPLS Circuit (50Meg). I also added an as-path prepend to ROUTER A to make the routes going out to the MPLS provider less preferred than what was being advertised by ROUTER B, which is now active. For the most part, everything is working just fine, however, I noticed that we were getting low UPLOAD Speeds out to the INTERNET. At the moment our DOWNLOAD speeds are 40ishMeg and our UPLOAD speeds are 3-4Meg. This is not normal as our other remote sites that have 50Meg circuits are able to achieve speeds much greater also before I made the HSRP changes to make ROUTER B primary, the upload speeds were around 7-8Meg on the 10Meg Circuit. The MPLS provider told me that their PE device is configured for SPEED 100 and FULL-DUPLEX which has been configured on my device as well. I do not see any fragments our CRC/Input errors on ROUTER B and traces TO and FROM the internet take the same path with low latency so it feels like the issue is local to the site, however I am not sure what the issue is.....
