    Hi, I am using Juniper MX104 as a Internet gateway router . We have two internet links with Ebgp . We planned to go for full routes from both the ISP . I need your suggestion on the following 1) Whether MX104 is capable of receiving full routes from two different ISP . 2) Maximum routes that can be learned by the MX104. 3) Best practices or precautions that need to be taken before receiving full routes from ISP . Routing Engine : RE-MX-104 Thanks Mahesh

    Hi Mahesh,

    2 ISP links can be configured with full BGP table.

    You can go through the below thread for more details on MX104

    Hi Mahesh,

    MX104 is powerful box which is optimized for aggregating mobile, enterprise WAN, business, and residential access services. The router is a high-performance router functioning as a universal aggregation platform for mobile broadband and metro Ethernet applications.

     

    However, I would personally suggest not to consume 2 Full routing tables; unless otherwise there is some real requirement to play with prefixes. Since, learning of 2 Full Internet feed will consume a good amount of Memory/CPU resources of the box.

    1) Whether MX104 is capable of receiving full routes from two different ISP .

    Yes, if the only major purpose of the device is dual peerings and a merged internet table the device should be fine for the services.  But as Python as mentioned this routing capacity and management will be a significant percentage of the FIB so I would not load a number of other services on the device.

     

    2) Maximum routes that can be learned by the MX104.

    FIB 1 million RIB 4 million with the current internet active table being under 700 k right now.

     

    3) Best practices or precautions that need to be taken before receiving

    For this type of setup, I would establish the sessions one at a time and add the second one after hours.  During convergence routing paths will change and can have minor effects on existing flows to internet sources.  But this is a pretty simple setup without much complication.
