Can I add routes to rt_tables by hand with the vi editor? If I add a route to that file, it will be there if I reboot the box? I am sure there are stupid questions but I can''t find the answer into the papers I have here. Luis Miguel Cruz Miranda. CCNA - Systems Administrator ________________________________________...

...as a default gateway? Do I have to remove it? 2. In the scenario with 4 NICs, one routing table each, and another routing table doing load balance, Do the tables that imply routes that are being used by the load balance routing table have to be removed? p.e. : echo 255 local > /etc/iproute2/rt_tables echo 254 main >> /etc/iproute2/rt_tables echo 253 default >> /etc/iproute2/rt_tables echo 0 unspec >> /etc/iproute2/rt_tables echo 200 balanceo2 >> /etc/iproute2/rt_tables echo 201 cable >> /etc/iproute2/rt_tables echo 202 cable2 >> /etc/iproute2/rt_tables...

Which files do I need to edit in order to initialize a route after a reboot. I have a 802.1q tagged VLAN interface which I need to create a rule, and a route for. I see on my CentOs 4.2 box that in /etc/iproute2 there are the following files. I realize that I can add my tables to /etc/iproute2/rt_tables, but when I want to create a rule I am not sure where to put the information for the next reboot.

...o now have 2 ISP, one DSL and one cabel. I want to use the DSL as my primary and only use the cabel-modem if the DSL fails. The setup is: IP1 -> Router -> NAT_IP1 -> eth0 -> eth2 (LAN) IP2 -> Cable-Modem -> eth1 -> eth2 (LAN) I wrote the following in my /etc/iproute2/rt_tables ip rule add from NAT_IP1 lookup 1 ip route add 10.1.0.0/16 via 10.1.1.1 table 1 ip route add 0/0 via NAT_IP1 table 1 ip rule add from IP2 lookup 2 ip route add 10.1.0.0/16 via 10.1.1.1 table 2 ip route add 0/0 via IP2 table 2 The problem is identical to http://www.samag.com/documents/s=1824/sam0...

Hello. I have the problem that I have two gateways on the same subnet, 80.237.244.1 and 80.237.244.33. Both gateways are 100 MBit cards, so I have 2 times 100 MBit to the Internet. The NIC in the server is a gigabit-card, so this card is easy able to use both gateways for outgoing traffic. Now I just want to use both gateways for my outgoing traffic but no matter what I do, it doesnt work. I

Hi all; I have a custom iproute2 table and a few rules to go along with it (CentOS 5) -- I have added the table to /etc/iproute2/rt_tables. if-up and friends doesn't seem to handle this real gracefully. How are those of you out there doing something similar managing this customization? I don't really want to muck with /etc/init.d/network or the if-up scripts to avoid breaking upgrades. rc.local my best bet? Thanks, Ray
