@PhoneBoy Agreed that solution provides for internet traffic through another ISP, when I put similar PBR for particular VLAN all the traffic including internal subnet also forwarded to ISP link, herewith I have attached simplified network overview.
1. ISP 1 - Primary INT
2.ISP 2 - Specific user internet access (managers)
3.ISP 3 - Specific server segment internet access
Near Future expansion
4. ISP-4 SIP link for softPBX server
5.ISP-5 secondary internet going to participate ISP redundancy
I believe PBR table would be enormous also very hard to manage, Please suggest best practice to maintain less configuration to fulfill the requirement (please consider MPLS network will be used by users/servers to access some service from corporate network)
