quick question CSR on AWS with TGW setup

[sateeshk10]

Hi guys,

Did any one tried CSR in TGW setup if so, assuming we don`t need IAM policy for route table change during HA event ?

The videos shown in YouTube for Ha is without TGW  so, i am think with TGW should be bit different for HA setup , don`t need any changes on AWS RT`s or eni`s if CSR01 is down??

here is the flow..

spoke VPC - TGW - Connect (BGP over GRE, instead of ipsec)  - CSR- BGP over IPSEC to on-prem 

Between CSR`s , am running IBGP over GRE tunnel , incase of CSR01 is down traffic switch quickly to CSSR02 without any special cloud redundancy  commands ?

My question is focused on how to HA setup only..!
