RE: LLDP via SNMP

2016-05-26 Thread Michael Hare
My experience with Juniper has been mixed, experience with 12.X and 13.X made me wonder if I had a poor understanding of how to do a proper decode or if Juniper's implementation itself had issues as I would often get incomplete results. We've now grab over XML and have been pleased with that ch

I'm not against the theory of what is being proposed, but I was surprised to see little discussion of this announcement on list. Upon examination on my view of the DFZ from AS3128 I see over 400 upstream routes falling into this category, mostly in the 64512 - 65534 range. Based on our flow ba

RE: Long AS Path

Couldn't one make the same argument with respect to filtering private ASNs from the global table? Unlike filtering of RFC1918 and the like a private ASN in the path isn't likely to leak RFC1918 like traffic, yet I believe several major ISPs have done just that. This topic was discussed ~1 year

While attempting to focus on ISPs there is still [unbelievably] a vendor support issue. You may consider this a procurement failure, but the fact remains that some products [Cisco me3400e] have yet to implement support. -Michael On 8/9/2011 9:24 AM, Nick Hilliard wrote: On 09/08/2011 14:47,

nt on entry. Fine, that is their choice. There are other vendors offering 4 byte ASN in simliar products at or near this price point and we'll probably have to move to them. -Michael On 8/9/2011 10:38 AM, Nick Hilliard wrote: On 09/08/2011 15:45, Michael Hare wrote: While attempting to foc

Martin- I represent a statewide educational network running Juniper gear that is a quasi-enterprise. I think efforts depend on size and type of network. We are testing an approach that involves; 1) whitelisting known local resolvers, well behaved cloud DNS resolvers. 2) on ingress, policing

Mark (and others), I used to run loose uRPF on peering/transit links for AS3128 because I used to think that tightening the screws was always the "right thing to do". I instrumented at 60s granularity with vendor J uRPF drop counters on these links. Drops during steady state [bgp converged]

Paul- You said: "... would decide to configure MPLS paths between Chicago and distant international locations ..." AS3128 runs MPLS and it's probable someone might correct me here, but for a IGP backbone area I think it's common for there to be a full mesh of LSPs via either LDP, RSVP, SR etc.
