1 Hi,

5 This is quite a large list with lots of hosts, but even grep –v the larger /24-ones leaves the arp-table up to 10.000…
6
7 I’ve also heared (but never understood), that the lo-interface should be up and running. This is true in this case, but I noticed, the routes for 127.0.0.1 are missing in some tables.
8
9 I slightly doubt, that this is the root-cause for the exploding arp-cache, but I though it’s worth mentioning.

382 Can you post the output of "ip rule sh"?
383
384 And for every table listed in the above, post the output of "ip route sh table $TABLENAME"?
