What does this route map modification mean?

Are the "123.123.123.123" addresses really the exact same in the setup you are debugging - or are they slightly different? Assuming they are different - the first line means that anything in the network defined by 123.123.123.123/30 should be forwarded to 10.10.3.14. The second line means the specific IP address 123.123.123.123 should be forwarded to 10.10.3.13. As to why - we'd need more context. Can you tell me the last octet (the last .123) specifically - what exactly is it in your situation. Having two of htem the same with two different netmasks is a bit weird, and could mean a couple of different things....

First line: packets to hosts at 123.123.123.123/30 are routed via 10.10.3.14, except (second line) for packets to 123.123.123.123/32, which are routed via 10.10.3.13. However, I suspect a anonymization error, if you really define a /30 network, the first address (same ip/32) is the "network"-address, which doesn't really get packets. It could also be, that someone tries to route a slice out of a bigger subnet differently, but it smells funny...
