redistribute {bgp as-number | connected | rip | static} [level-1 level-1-2 | level-2] [metric
metric-value] [metric-type {external | internal}] [route-map map-name]
Configure the following parameters:
• level-1, level-1-2, or level-2: assign all redistributed routes to a level. The default is level-2.
• metric-value: the range is from 0 to 16777215. The default is 0.
• metric-type: choose either external or internal. The default is internal.
• map-name: enter the name of a configured route map.
• Include specific OSPF routes in IS-IS.ROUTER ISIS mode
redistribute ospf process-id [level-1| level-1-2 | level-2] [metric value] [match external {1
| 2} | match internal] [metric-type {external | internal}] [route-map map-name]
Configure the following parameters:
• process-id: the range is from 1 to 65535.
• level-1, level-1-2, or level-2: assign all redistributed routes to a level. The default is level-2.
• metric value: the range is from 0 to 16777215. The default is 0.
• metric value: the range is from 0 to 16777215. The default is 0.
• match external: the range is 1 or 2.
• match internal
• metric-type: external or internal.
• map-name: name of a configured route map.
To view the IS-IS configuration globally (including both IPv4 and IPv6 settings), use the show running-config isis command in
EXEC Privilege mode. To view the current IPv4 IS-IS configuration, use the show config command in ROUTER ISIS mode. To view the
current IPv6 IS-IS configuration, use the show config command in ROUTER ISIS-ADDRESS FAMILY IPV6 mode.
Configuring Authentication Passwords
You can assign an authentication password for routers in Level 1 and for routers in Level 2.
Because Level 1 and Level 2 routers do not communicate with each other, you can assign different passwords for Level 1 routers and for
Level 2 routers. However, if you want the routers in the level to communicate with each other, configure them with the same password.
To configure a simple text password, use the following commands.
• Configure authentication password for an area.
ROUTER ISIS mode
area-password [hmac-md5] password
The Dell OS supports HMAC-MD5 authentication.
This password is inserted in Level 1 LSPs, Complete SNPs, and Partial SNPs.
• Set the authentication password for a routing domain.
ROUTER ISIS mode
domain-password [encryption-type | hmac-md5] password
The Dell OS supports both DES and HMAC-MD5 authentication methods.
This password is inserted in Level 2 LSPs, Complete SNPs, and Partial SNPs.
To view the passwords, use the show config command in ROUTER ISIS mode or the show running-config isis command in
EXEC Privilege mode.
To remove a password, use either the no area-password or no domain-password commands in ROUTER ISIS mode.
Setting the Overload Bit
Another use for the overload bit is to prevent other routers from using this router as an intermediate hop in their shortest path first (SPF)
calculations. For example, if the IS-IS routing database is out of memory and cannot accept new LSPs, Dell EMC Networking OS sets the
overload bit and IS-IS traffic continues to transit the system.
To set or remove the overload bit manually, use the following commands.
• Set the overload bit in LSPs.
