Hi All,
so just want some clarity on limitations or issues that i can expect to run into..
we have a PAN NGFW with 2x ISP links and want to do load balancing over these for internet traffic.
ECMP seems to be the way to go and fairly straight forward to setup..
However, we will also have a primary and secondary IPSEC tunnel into Azure from this NGFW which uses BGP for route selection that peers with BGP on the Azure side.
do I need to do anything specific on BGP for the IPSEC tunnels not to be affected.
do i need to enable 'ecmp multiple as support' in BGP? or not needed
Plan is quite simple..
enable ecmp, enable strict routing for the ipsec tunnels.
make sure policies/nats in place to allow traffic (both ISPs belong to same untrust zone).
any red flags i should look out for?
thanks in adv
