Hi everyone,
Recently I studied the BGP AS path looping problem, and found that in
most cases, the received BGP routes containing local AS# are suspicious.
However, we checked our BGP routing table (AS23910,CERNET2) on juniper
router(show route hidden terse aspath-regex .*23910.* ), and have

I have a Cisco IOS specific question for the group and also specifically
related to the 6500 platform. We have always been very conservative with our
IOS version that we run in production, we are still running a pretty old safe
harbor build of 12.2.x on SUP 720 3BXLs with BGP and OSFP routing.

They are saying this CPE has no ALG in it, but they can enable DMZ, which
acourse made zero difference.
What I do find funny is they escalated the problem to Tier-2 and wanted to
enroll the customer in premium tech support for $15 a month, because the

Easy to make a switch when the only thing you're actually doing is
teling the asic what to do (Cumulus, Ubiquiti, ... every other broadcom
vendor out there...)
Better yet - Atheros have finally come out with a 24*1GE + 2*10GE switch

You could try to build simple router with DPDK yourself. It's very
straightforward and have good examples for simple routing.
I have done some tests with PF_RING ZC (it's very similar technology
to DPDK without specialization on building of network devices) while
test my DDoS monitoring
Anyone aware of any dpdk enabled solutions in the software routing space
that doesn't cost an arm and a leg?
vMX certainly does.

I propose the hybrid solution:
A device such as the ZTE 5960e with 24x 10G and 2x 40G will set you about

This thing can do MPLS and L3 equal cost multiple path routing. With that
you can load balance across as many software routers as you need.
It also speaks BGP and can accept
