Hello, and thanks for your time and attention. I am trying to determine the best method of significantly reducing the memory usage on one of our J6350 routers (Rtr-1) without causing too many new problems. The over-utilization is due to the BGP routing table size.
Our current ideas and considerations:
- completely remove BGP on Rtr-1 and any associated configuration on the BGP neighbors
- possibly distribute a default route to Rtr-1 without advertising it to the upstream OSPF neighbors
- possibly create OSPF stub
Any and all responses are appreciated.
Current configs:
