configure ospfv3 virtual-link authentication

configure ospfv3 virtual-link {routerid} router-identifier {area} area-identifier authentication [none | keychain keychain-name | ipsec spi spi esp-auth-algorithm algorithm key [key-string | encrypted encrypted-key-string]

Description

Configure Internet Protocol Security (IPsec) with a manual key to provide authentication on OSPFv3 virtual-links.

Syntax Description


ospfv3	Specifies OSPFv3 virtual-link.
virtual-link	OSPFv3 virtual link.
routerid	OSPFv3 router ID.
`router-identifier`	Specifies the router identifier of the advertising router.
area	OSPFv3 area.
`area-identifier`	Specifies an OSPFv3 area, a four-byte, dotted decimal number.
authentication	Specifies interface authentication.
none	Specifies no authentication (default).
keychain	Specifies the authentication method is keychain.
`keychain-name`	Specifies the keychain name.
ipsec spi	Specifies the authentication type is IPsec Encapsulating Security Payload (ESP) with manual key.
`spi`	Specifies Security Parameter Index value. Range is 256-4294967295.
esp-auth-algorithm	Specifies the ESP Authentication algorithm.
`algorithm`	Specifies the authentication algorithm. Supported authentication algorithms are hmac-sha-1 and hmac-sha-256.
key	Specifies the authentication key,
`key-string`	Specifies the key string in clear text. Both the ASCII string and hexadecimal string are supported, and hexadecimal string must begin with “0x”.
encrypted	Specifies that the key string is in encrypted format.
`encrypted-key-string`	Specifies the encrypted key string. The encrypted key string must be enclosed in double quotes.

Default

If not specified, no authentication is applied.

Usage Guidelines

When configuring IPsec with a manual key on an OSPFv3 virtual link, the exact same IPsec parameters (SPI, algorithm and key-string) must be specified on all routers connected to both sides of the virtual link.

To configure OSPFv3 VLAN authentication, run the command configure ospfv3 [{vlan} vlan-name | {tunnel} tunnel-name] authentication [none | keychain keychain-name | ipsec spi spi esp-auth-algorithm algorithm key [key-string | encrypted encrypted-key-string].

Example

The following example for virtual-link "5.5.5.5 0.0.0.2" applies authentication type IPsec with SPI "1001" and algorithm "hmac-sha-1" with key "mykey":

# configure ospfv3 virtual-link 5.5.5.5 0.0.0.2 authentication ipsec spi 1001 esp-auth-algorithm hmac-sha-1 key mykey
