I've asked for this feature several years ago and evidently it is not trivial to increase the number of routing tables.
But, perhaps someone now has time & inclination? I would like to have more (a few thousand) routing tables available in the kernel so that I can use a routing table for each of my many VLANs. Currently, the netlink protocol only specifies an 8-bit id for the routing table: http://www.faqs.org/rfcs/rfc3549.html Section 3.1.1 so a new netlink message would need to be created and the 'ip' tool updated. I think at least a 16-bit identifier should be used, possibly a full 32 bits so we don't have to revisit this again for a while! The kernel itself would also need to be modified so that it can have more routing tables. I realize most people don't need a large number of tables, so the maximum number should be configured at either compile time or run time. If I remember right, there are certain tables (253 - 255) that are currently special in the kernel. For complete backwards compatibility, this hole would probably have to remain as it is, with the new tables starting at 256. I would be willing to help test any resulting patches, and can also offer bribes of money, hardware, beer, etc. Thanks, Ben -- Ben Greear <[EMAIL PROTECTED]> Candela Technologies Inc http://www.candelatech.com - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
