Two ISP on BGP and OSPF, Two Network & one router

[Yunawan Mr]

Hi, I have 1 router (Cisco ASR1002), 2 ISP Link (ISP 1 have 2 AS Number & ISP 2 not have AS Number) & 2 networks(one is 172.16.0.0 & another is 192.168.0.0).  I want to pass 2 networks by 2 different ISPs, like 172.16.0.0 will be passed by ISP 1 & 192.168.0.0 will be passed by ISP 2. I have 1 firewall ASA 5525 attached with this router. Design like this but router use ASR1002 not 2921 and Firewall use ASA5525 not 5520

How can i do this in 1 router that  two network will be divided by two ISPs? How the natting will be done for 2 link??

Can anyone please help me in this issue urgently??

You need to use PBR. See this link which covers pretty much everything you are trying to do -

Hi Jon Marshall, Thanks for your reply.

My router has 6 links, 3 for ISP1 use AS number BGP Routing & 2 for ISP2 use OSPF and 1 for Lan which is actually connected with firewall not switch. In Firewall we have 2 link for LAN

Nat is implemented on router ASR1002. We are using ASA 5525 firewall.

Another question, is it possible to merge 2 different ISP connections so that I have doubled bandwidth in ASR1002 router?

Hi this is possible you can get this done quickly once you are comfortable with configuring route-maps
