Hi Curt,
The metric transparent command is used to redistribute MPBGP routes into
RIP. This is usefull when using RIP as the PE-CE routing protocol for a
VPN. Routes learned via RIP are redistributed into the MPBGP
address-family and the metric for each RIP route is translated to the
BGP MED value. At the far end, the MPBGP routes are redistibuted back
into RIP and with the "metric transparent" commmand, the MED value is
translated back into the RIP metric.
Here is more info:

Curt,
Lots of these "mystery commands" relate to MPLS. Here is a quote from
MPLS and VPN Architectures :
metric transparent. This command causes RIP to use the routing table
metric for redistributed routes as the RIP metric, with the original
metric being carried across the MPLS/VPN backbone in the BGP MED value.

Subject: Metric transparent ??
Team,
I noticed a new keyword that I haven't seen before today. I only seem
to see it under the rip routing process when redistributing. It is
"metric transparent" at the end of a redistribute statement under rip.
For example:
R2#
R2#config t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#router rip
R2(config-router)#redistribute ospf 10 metric ?
<0-16> Default metric
transparent Transparently redistribute metric
This was done on a 3640, using IOS 12.4(5)
(c3640-jk9o3s-mz.124-5.bin)
Does anyone know what this keyword does, how it works, and/or have any
links to the documentation on this keyword. I've checked the docCD
under IOS 12.4 and didn't see anything under rip, nor under the master
command list. Searching for "metric transparent" only shows me links
to
MPLS-related topics.
If anyone can help me understand what this keyword does, I'd really
appreciate it.
TIA,
Curt
