[Mark Tech]

Hi all
  Thanks all for your input, I will modify the cam-profile and ip-cache allocation

  Certainly choosing the appropriate cam-partition profile is recommended, as the memory allocation will be  optimized to better fit your needs. This will free up space that you would potentially never use (ipv6, vpnv4, L2 VPN). In any case, if you don’t use the proper profile, you won’t be able to allocate the maximum value. Also you certainly have some headroom to increase system-max values if you want to.

    Hi all

    Thanks for that. I have just tested it and I can now see that all routes are installed on the card by increasing to 256000

     

    # sh ip network
Total IP and IPVPN Cache Entry Usage on LPs:
 Module        Host    Network       Free      Total
      1          10     225374      30616     256000

     

    My question now is; are there any reasons now not to increase system-max ip-route and system-max ip-cache to 524288 and alter the cam-partition profile to ipv4 as all this box will ever do is push ipv4 routes and receive multiple full BGP internet routes. This is to avoid any reloads in the near future. 

     

    It will never be used for ipv6, vpvn4 etc

     

    Your thoughts are appreciated

     

    Regards

    Also check your Cam Partition Profile to see if you need to change it.

        Mark,
You will have to increase the default ip-route hardware entry table, and as well as the ip cache table. Here are the commands.

telnet at NetIron MLX-16 Router(config)# system-max ip-route 256000 
telnet at NetIron MLX-16 Router(config)#system-max ip-cache 256000 

the 256000 value is just a sensible value based on the current internet routing table size (~225k).

A reload is required.

              I have just installed  an MLX and connected it to my existing internet Cisco routers. The MLX is reciving full BGP routes and they are seen in the BGP table however I am seeing this in the log


       


      Sep  5 18:47:30:I:Warning: MODULE 1 - No free cache entry for new route
Sep  5 18:46:29:I:Warning: MODULE 1 - No free cache entry for new route
Sep  5 18:46:21:I:Warning: MODULE 1 - cannot allocate free cache entry


       


      sh ip network
Total IP and IPVPN Cache Entry Usage on LPs:
 Module        Host    Network       Free      Total
      1          10     102390          0     102400


      
sh ip cache
Total IP and IPVPN Cache Entry Usage on LPs:
 Module        Host    Network       Free      Total
      1          10     102390          0     102400


           


      Hence all internet routes are not being installed on  to the card, how can the ip cache be increased?


      Or have I missed something
