Hi,
Thanks for Reply.
your point related asymmetric routing is valid.
i want that traffic coming from ISP-1 should go back through same ISP-1.
i will use unset flow reverse-route clear-text to avoid asymmetric routing.If i need anything else for this please let me know.
A records can be updated dynamical??? i didn't understand your point,can you eloberate this for my better understanding.
