Chapter 26 GRE and DM VPNs
GRE and Dynamic GRE VPNs
Hold Time
(EIGRP only.)
The number of seconds the router will wait to receive a hello message
before invalidating the connection. The range is between 1 and 65535.
The default hold time is 15 seconds (three times the hello interval).
Delay
(EIGRP only.)
The throughput delay for the primary route interface, in microseconds.
The range of the tunnel delay time is 1-16777215. The default is 1000.
Failover Delay
(EIGRP only.)
The throughput delay for the failover route interface, in microseconds.
The range of the tunnel delay time is 1-16777215. The default is 1500.
Bandwidth
(EIGRP only.)
The amount of bandwidth available to the primary route interface for
the EIGRP packets. You should enter a value that gives priority to the
primary route over other routes.
You can enter a value in the range 1 to 10000000 kb. The default is 1000
kb.
Note By default, the cost of sending a packet on an interface is
calculated based on the bandwidth—the higher the bandwidth,
the lower the cost.
Failover Bandwidth
(EIGRP only.)
The amount of bandwidth available to the failover route interface for
the EIGRP packets.
Enter a value in the range 1 to 10000000 kb. The default is 1000 kb.
Process Number
(OSPF only.)
The routing process ID number that will be used to identify the secured
IGP that Security Manager adds when configuring GRE.
The range is between 1 and 65535. The default is 110.
Security Manager adds an additional Interior Gateway Protocol (IGP)
that is dedicated for IPsec and GRE secured communication. An IGP
refers to a group of devices that receive routing updates from one
another by means of a routing protocol. Each “routing group” is
identified by the process number.
For more information, see Understanding GRE, page 26-2.
Hub Network Area ID
(OSPF only.)
The ID number of the area in which the hub’s protected networks will
be advertised, including the tunnel subnet. You can specify any number.
The default is 0.
Spoke Protected Network
Area ID
(OSPF only.)
The ID number of the area in which the remote protected networks will
be advertised, including the tunnel subnet. You can specify any number.
The default is 1.
Authentication
(OSPF or RIPv2 only.)
A string that specifies the OSPF or RIPv2 authentication key. The string
can be up to eight characters long.
Cost
(OSPF or RIPv2 only.)
The cost of sending a packet on the primary route interface.
If the selected protocol is OSPF, enter a value in the range 1-65535; the
default is 100.
If the selected protocol is RIPv2, enter a value in the range 1-15; the
default is 1.
