isisd: Attached-bit in LSP header
Set/reset attached-bit in LSP header:
This patch provides support for set/reset attached_bit in the LSP header.
In IS-IS networks, routing inter-area traffic from L1 areas is
accomplished by sending the traffic to the nearest L1/L2 router.
A L1/L2 router identifies itself by setting an attach-bit (ATT-bit) in its (LSP).
The ATT-bit in LSP can be changed using the set-attached-bit or
no-set-attached-bit commands (similar to ‘set-overload-bit’ and
'no set-overload-bit’) using telnet terminal in router configuration mode.
Steps:
enable
configure terminal
router isis <Routing area>
set-attached-bit
V2: Removed looping through area list as this well set the bit for all
areas in the list. This implementation now looks exactly like the
current overload bit implementation.
