3.4.1.3 Defining an ELAN
Each ELAN is defined by an address statement whose value denotes the ATM
address of the ELAN’s LES. For example:
engineering.Address: 47000580ffe1000000f21a01b90020480605b211
If you wish to define multiple instances of an ELAN for use by the LEC
failover mechanism, the address statements would appear as follows:
marketing|0.Address: 47000580ffe1000000f21a01b90020480605b221
marketing|1.Address: 47000580ffe1000000f21a01b90020480605b223
marketing|2.Address: 47000580ffe1000000f21a01b90020480605b225
In this example, redundant LES addresses for the
marketing
ELAN have
been defined. Note that the group name,
marketing
, ends with the meta-
character
|
, followed by a number indicating the position of the LES in the
failover sequence. If the
marketing|0
LES were to fail, LECs could “failover”
to the
marketing|1
LES. The LEC then periodically tries to reconnect with
marketing|0
. If
marketing|1
also failed, the LEC would then failover to
marketing|2
, (and periodically attempt to reconnect to
marketing|0
and
marketing|1
).
In addition, you may instruct a given ELAN to override any of the default
values. For example, the
engineering ELAN could override the default
Maximum_Frame_Size of 1516; thus:
engineering.Maximum_Frame_Size: 4544
