[j-nsp] Question on BGP Peering/Upstream STM1-Juniper

Mon Feb 23 15:14:03 EST 2009

Thanks Mark..for ur info...

For information...iam using cSTM1... ..if my customer request for 4M internet via ethernet port..then i will request from my upstream for 4M internet...may i know how is the configuraton here....

network diagram shall be like this...

customer(4M-fe)-----static ip-------(fe)M10i(cstm1)----bgp----(stm1)Upstream

TQ

GRE Keepalives are *still* not supported?  I remember asking for this
in an enhancement request almost 5 years ago... geez...

Does BFD work on GRE?

Hai...
?
Need some info and guideline.
?
I am newbies and this is the first time handling the m10i router. my compny
want to setup layer 3 network. and upstream with one provider stm1
?
M10i------STM1-------Upstream Provider
?
run bgp between both router.?This stm1 will be the trunk and our upstream
initially will provide perMeg basis in this trunk...initally 1xE1 until the STM1
trunk full capasity. Interconnection is STM1 but the internet?provided by
upstream is E1. may i know how is the setup here. please help me....please
assist...as iam vry puzzle here.
?
TQ

Not as a protocol to bring down the GRE tunnel.

You can use OSPF with BFD though and make the tunnel endpoints known via 
OSPF.
I know it's not ideal, but it'll work.

There's two possibilities here:

a) You're running a channelized STM-1 PIC, which can get you
   n x E1 logical circuits.

b) You're running a clear-channel STM-1 PIC, and your
   upstream will likely use policing to limit your bandwidth
   to/from them to 2Mbps increments, or as your contract
   permits.

I'd recommend the latter, less configuration hassle given 
the application.

Channelized STM-1 makes more sense for customer PE-side 
customer aggregation in n x E1 increments.

Cheers,

Mark.
