1-63
destination-ip-address
: Destination IP address for the sham link.
cost
: Cost for the sham link, one by default.
dead-interval
: Dead Interval in seconds, 40 seconds by default. It must be equal to the
dead interval of the router on the other end of the virtual link and be at least four times
the hello interval.
hello-interval
: Interval at which the interface sends Hello packets, 10 seconds by
default. It must be equal to the hello interval of the router on the other end of the virtual
link.
retrans-interval
: Interval at which the interface retransmits LSAs, five seconds by
default.
delay
: Delay interval before the interface sends an LSA, one second by default.
simple
[
cipher
|
plain
]
password1
: Uses simple authentication. If you specify neither
the
cipher
nor the
plain
keyword, the
password1
argument is a string of 1 to 8
characters. For the plain mode, the
password1
argument is a string of 1 to 8 characters.
For the cipher mode, the
password1
argument can be either a string of 1 to 8
characters in plain text, or a string of 24 characters in cipher text.
md5
: Uses MD5 algorithm for authentication.
hmac-md5
: Uses HMAC-MD5 algorithm for authentication.
key-id
: Authentication key ID of the interface, in the range 1 to 255. It must be the same
as that of the peer.
cipher
: Uses cipher text.
plain
: Uses plain text.
password2
: Password string, case sensitive. If you specify neither the
cipher
nor the
plain
keyword, it is a string of 1 to 16 characters in plain text or a string of 24 characters
in cipher text. For the plain mode, it is a string of 1 to 16 characters. For the cipher mode,
it can be either a string of 1 to 16 characters in plain text, or a string of 24 characters in
cipher text.
Description
Use the
sham link
command to configure a sham link.
Use the
undo sham link
command with no optional keyword to remove a sham link.
Use the
undo sham link
command with optional keywords to restore the defaults of
the parameters for a sham link.
If two PEs belong to the same AS and a backdoor link is present, a sham link can be
established between them.
For plain text authentication, the default authentication key type is plain. For
authentication using MD5 algorithm or HMAC-MD5 algorithm, the default
authentication key type is cipher.
