Delete a Non-Persistent IPv4 or IPv6 Static RouteDelete a Non-Persistent IPv4 or IPv6 Static Route
Use this procedure to remove a non-persistent IPv4 or IPv6 static route.
Before you begin
You must access the appliance operating system to delete a static route. For information, see Operating System Access.
Procedure
-
Log on to the appliance with the user name rsaadmin and the operating system password.
-
For a list of the available static routes, you can view the current routing tables.
-
For IPv4, do the following:
-
To show the main routing table, type:
sudo ip -4 route show
-
To show the table in the network interface routing file, type:
sudo ip -4 route show table Tetho
where:
Teth0 specifies the table in the network interface routing file, such as Teth0 for the interface eth0.
-
-
For IPv6, do the following:
-
To show the main routing table, type:
sudo ip -6 route show
-
To show the table in the network interface routing file, type:
sudo ip -6 route show table Tetho
where:
Teth0 specifies the table in the network interface routing file, such as Teth0 for the interface eth0.
-
-
-
Choose one of the following options:
-
To manually delete a non-persistent IPv4 static route, without restarting network services or rebooting the Authentication Manager instance, do the following:
-
Delete the route from the interface. Type the following, and press ENTER:
sudo ip route del destination/nn via gateway dev eth0
where:
-
destination specifies the the IP address of the network or host for which you are deleting the static route.
-
/nn is the prefix length notation used to specify the subnet mask associated with the destination IP address.
-
gateway specifies the IP address of the node that will route traffic to the destination network or host.
-
eth0 specifies the network interface, for example, eth0 or eth1.
-
-
Delete the route from the interface table. Type the following, and press ENTER:
sudo ip route del destination/nn via gateway dev eth0 table Teth0
where:
-
destination specifies the the IP address of the network or host for which you are deleting the static route.
-
/nn is the prefix length notation used to specify the subnet mask associated with the destination IP address.
-
gateway specifies the IP address of the node that will route traffic to the destination network or host.
-
eth0 specifies the network interface, for example, eth0 or eth1.
-
Teth0 specifies the table in the network interface routing file, such as Teth0 for the interface eth0.
-
-
-
To manually delete a non-persistent IPv6 static route, without restarting network services or rebooting the Authentication Manager instance, do the following:
-
Delete the route from the interface. Type the following, and press ENTER:
sudo ip -6 route del destination/nn via gateway dev eth0
where:
-
destination specifies the IP address for the network or host for which you are deleting the static route.
-
/nn is the prefix length notation used to specify the subnet mask associated with the destination IP address.
-
gateway specifies the IP address of the node that will route traffic to the destination network or host.
-
eth0 specifies the network interface, for example, eth0 or eth1.
-
-
Delete the route from the interface table. Type the following, and press ENTER:
sudo ip -6 route del destination/nn via gateway dev eth0 table Teth0
where:
-
destination specifies the IP address for the network or host for which you are deleting the static route.
-
/nn is the prefix length notation used to specify the subnet mask associated with the destination IP address.
-
gateway specifies the IP address of the node that will route traffic to the destination network or host.
-
eth0 specifies the network interface, for example, eth0 or eth1.
-
Teth0 specifies the table in the network interface routing file, such as Teth0 for the interface eth0.
-
-
-
To automatically delete all non-persistent IPv4 and IPv6 static routes, you can restart the network services on the Authentication Manager instance. Network services will not be available for several seconds. Type:
sudo service network restart
and press ENTER.
