We have Dual homed topology. one ISP internet link is connected to one ASR and another ISP internet link is connected to another ASR.
We are looking at all options to load share the internet links - ASRs will be configured to install all internet routes not just default route.
We would like to see if We can prefer ISP connected to ASR1 for all EMEA IP CIDR ranges and ASR2 for AMER region IP CIDRs.
could someone advise if Internet -Network prefixes contain standard community values when they are originated from one particular region in the globe. for ex:- advertisements originated in AMER region to contain XYZ:1234 community value.
So, We can match this community on ASR2 to increase LP so ASR1 also sends traffic for AMER destinations through ASR2
in short, if We have BGP regex to match routes originated from regions(AMER, EMEA , APAC, etc), please help me .
