Hello all,
I am a newbie at MPLS and I
have few questions.
1. Will the standard MPLS mibs like TE, LSR
and FTN mibs be implemented on all MPLS devices ? Does Cisco and Juniper
comply to the standard MIBs ? Or is there any variation.
The base MIBs have been implemented by
many
vendors including my company for several
years. I cannot
speak for JNPR, but perhaps someone from there can
write in. The thing
to keep in mind is
that they are just going for RFC status
now, so different
vendors may have implemented different
versions of the drafts over time. Hopefully now
with
RFCs that will change soon. Check the documentation of the
vendors
you
are intersted in for implementation
specifics.
As I am learning I was able to build a simple LSP
and Tunnel from a 4 node network(2 LER and and 2 LSR)
2. I was trying to get the FTN Mib from the
oidview.com and I realized they didnt have it.Apart from the internet draft is
there a location from which I can get the standard MIB ?
www.ietf.org.
Search for "FTN MIB" or look under the MPLS WG's web
page.
3. Assuming I have 2 VoIP traffic (for 2
different destination )which I like to model with 2 seperate tunnels in my
test environment, should I use the FTN Mibs to ensure traffice to gets routed
to appropriate tunnels ?
No MIB
can be used to ensure that traffic gets anywhere. *) The MIB will
only
tell you were the device thinks it is going. To tell where it is
actually going
you might have to test it to make sure it is getting there.
*)
4. Does Cisco/Juniper implement FTN Mibs in
their devices ?
Cisco has plans to release
the FTN MIB in the near future.
5. If there are IP packets about to enter
the MPLS cloud through the ingress routers, on what basis will IP packets be
routed to appropriate LSPs or tunnels.( Is that the reason why we need FTN ?
)
That
depends on local routing policy. The FTN MIB should show
you
all routes for traffic having the MPLS shim header
imposed at that LSR.
