Configuration restrictions and guidelines
When you configure a bypass tunnel on the PLR, follow these restrictions and guidelines:
Primary CRLSP
requires Bypass tunnel providing
bandwidth bandwidth protection
protection or not
No
The primary CRLSP can be bound
to the bypass tunnel when all the
following conditions are met:
•
•
Yes
After binding, the RRO message
carries the bandwidth protection
flag, and the bypass tunnel
provides bandwidth protection for
the primary CRLSP.
The primary CRLSP prefers bypass
tunnels that provide bandwidth
protection over those providing no
bandwidth protection.
The primary CRLSP can be bound
to the bypass tunnel when all the
following conditions are met:
•
•
No
After binding, the RRO message
carries the bandwidth protection
flag.
This bypass tunnel is selected only
when no bypass tunnel that does
not provide bandwidth protection
can be bound to the primary
CRLSP.
The bandwidth that the bypass
tunnel can protect is no less
than the bandwidth required
by the primary CRLSP.
There is not a CT specified for
the bypass tunnel, or the
specified CT is the same as
that specified for the primary
CRLSP.
The bandwidth that the bypass
tunnel can protect is no less
than the bandwidth required
by the primary CRLSP.
No CT that the bypass tunnel
can protect is specified, or the
specified CT is the same as
that of the traffic on the
primary CRLSP.
83
Bypass tunnel providing no
bandwidth protection
protection for the primary CRLSP,
and performs best-effort forwarding
for traffic of the primary CRLSP.
The primary CRLSP can be bound to
the bypass tunnel when one of the
following conditions is met:
•
No CT is specified for the bypass
tunnel.
•
The specified CT is the same as
that specified for the primary
CRLSP.
After binding, the RRO message
does not carry the bandwidth
protection flag.
This bypass tunnel is selected only
when no bypass tunnel that
provides bandwidth protection can
be bound to the primary CRLSP.
The primary CRLSP can be bound to
the bypass tunnel when one of the
following conditions is met:
•
No CT is specified for the bypass
tunnel.
•
The specified CT is the same as
that of the traffic on the primary
CRLSP.
After binding, the RRO message
does not carry the bandwidth
protection flag.
The primary CRLSP prefers bypass
tunnels that does not provide
bandwidth protection over those
providing bandwidth protection.
