frame-relay multilink [ack

<threshold>
| bid

| hello
<seconds>
| retry
<number>
]
Use the
frame-relay multilink
command to enable the Frame Relay multilink interface. When the
no
form of this command is issued, all configuration options associated with this command and binds made to
this interface are removed.
Syntax Description
ack
<seconds>
Optional. Specifies a wait for acknowledgement time (in seconds) for every
bundle link in the bundle. Range: 1 to 180 seconds.
bandwidth-class
Optional. Specifies the class of operation, placing a minimum limit on the
acceptable amount of bandwidth required for a bundle to initialize.
<class>
Optional. Specifies the class of operation. Range: a to c.
Class A
A single active link is sufficient for the bundle to be up.
Class B
All defined bundle links must be active for the bundle to be up.
Class C
A minimum threshold of links must be active for the bundle to be up.
<threshold>
Optional. Specifies the minimum number of active bundle links required for a
Class C bundle to be in the up state. This option will not be available unless
Class C is specified. Range: 1 to 65,535 links.
bid
<string>
Optional. Specifies a bundle ID (up to 48 characters) for the multilink bundle. All
hello messages sent on links belonging to the multilink bundle contain the bundle
ID. By default, the SROS creates a generic bundle ID for each configured multilink
bundle using the following:
MFR
<interface number>
where the interface number
corresponds to the interface number of the frame relay interface. For example, if
multilink is enabled on frame-relay interface 1, by default the bundle ID is
MFR1
.
Changing the bundle ID causes the multilink connection to go down for
renegotiation.
hello
<seconds>
Optional. Specifies the time (in seconds) between hello messages for every
bundle link in the bundle. Range: 1 to 180 seconds.
retry
<number>
Optional. Specifies the number of times a bundle link will retransmit a message
while waiting for acknowledgement. Range: 1 to 5 times.
Default Values
The default
ack
value is 4 seconds. The default
hello
value is 10 seconds. The default
<class>
value is a.
The default
retry
value is 2.
Functional Note
This command is different from
ppp multilink
. In
ppp multilink
, if multiple binds are configured for the
PPP interface without multilink PPP being enabled, the first link to bring up LCP will be the only link to
actually bind. In Frame Relay multilink, since there is no protocol corresponding to LCP, all binds will be
removed and the user will be free to re-issue any bind.
