Dynamic routes advertised from a virtual router appliance to TGW

Question

Dear Team - As per, https://www.amazonaws.cn/en/transit-gateway/faqs/

Number of Transit Gateway connect peers (GRE tunnels) per Transit Gateway Connect attachment = 4                                                           
  Dynamic routes advertised from a virtual router appliance to a Transit Gateway Connect peer = 1000

1) which means,  we can advertised up to 4000 routes in total from a virtual router appliance (Be it on-prem or VPC) to a Transit Gateway peers. Is this correct statement ?

2) If yes, then if i have 2000 routes on-prem, can i distributes first 1000 routes on first two GRE Tunnel and another 1000 routes on rest of two GRE tunnel ? this is for redundancy purpose.

3) same apply to below as well ?
Routes advertised from a Transit Gateway Connect peer to a virtual router appliance= 5000
so total 20,000 for 4 connect peer ?

Accepted Answer

Hi JD,

You are correct. Limit is per Peer so you can have 1000 routes per Peer .  So you can have 4K routes.
You can distribute routes as you mentioned in 2.
Number 3 is also correct.
