Need advice on optimizing my SP's network (MX80, BGP Full-View)

  • 1.  Need advice on optimizing my SP's network (MX80, BGP Full-View)

    Posted 05-26-2021 15:22

    I need some advice on how to optimize the core of the ISP network I work for.

    A simplified diagram of the network core looks like this:

    All routers here are PE routers. 
    Two routers ASBR1 and ASBR2 also act as route reflectors. ASBR1 and ASBR2 - МХ104, R1-Rn - МХ80.
    All routers holds BGP Full-View. Internet is in a separate VRF.
    The problem is - high memory usage on R1-Rn (~ 1.8 millions prefixes) About 95%. 

    I would like to get away from the scheme with Full-View on all routers (leaving full-view only on the ASBR1  & ASBR2 and 0/0 on R1-Rn).
    But how to balance traffic in this case? VRRP? Are there any other options?
