Note: When configuring a stub area, all routers within the stub area should configure
the area as a stub. The router connecting to the backbone typically defines the
default route onto the backbone.
Subnet Mask
Sets the bit mask for determining which portion of the IP address identifies the
subnetwork. Subnetworks (called subnets) are two or more physical networks
sharing a common network field (the NIC-as signed portion of the 32-bit IP address).
If the interface does have subnets, then enter the 32-bit subnet mask in dotted-
decimal notation.
Suppress
Authentication Traps
Suppresses the reporting of SNMP authentication failures to the configured trap
community. An authentication failure is the receipt of an SNMP request from an
unknown community. This feature informs the network manager of unauthorized
attempts to access the router via SNMP.
Default: Yes
No
Enables SNMP authentication trapping—SNMP traps the authentication failure and
alerts the network management station.
Yes
Disables SNMP authentication trapping—the network management station is not
alerted about unauthorized attempts to access the router via SNMP.
Tag
Enables the further specification of external routes.
Within OSPF external links advertisements, a 32-bit External Route Tag field is
attached to each route. The contents of this field are not used by OSPF but can be
used by source and destination routers.
Options
If you want to filter the contents of the External Route Tag field, enter the field
contents in eight-digit hexadecimal format.
Leave the field blank if you do not want to filter the contents of the field.
To Interface
Assigns a specific interface for receiving EGP, RIP, or OSPF updates when creating a
EGP, RIP, or OSPF import route filter.
Options
Enter the IP address of the interface in dotted-decimal notation if you want a
single interface to send all EGP, RIP, or OSPF updates to the import route filter.
Leave the field blank if you want the EGP, RIP, or OSPF filter to universally accept
updates from all interfaces.
To Protocol
Sets a export or import route filter to recognize EGP, RIP, or OSPF as the protocol
used for receiving routing information.
Default: RIP
