It's related to your hold timer and your convergence time. Lower to 14/45s and it will be much faster. On Wed, Apr 19, 2023, 5:31 PM Mark - Myakka Technologies wrote: > Trey, > > That is the main question. If it takes the rest of the Internet 10 mins > to figure out my BGP dropped, does it matt

Trey, That is the main question. If it takes the rest of the Internet 10 mins to figure out my BGP dropped, does it matter if I spend $ of some super fast router that can build the tables in 30s? -- Best regards, Markmailto:m...@mailmt.com Myakka Communication

Re: [AFMUG] BGP Question

You can prevent this by having a backup default route. The other thing is if you are n a physical interface or aggregated interface with a vlan on your upstream's router. If its physical it should stop routing traffic when it sees the interface down. If not it may keep trying to send traffic do

Re: [AFMUG] OTDR transmit power

As I recall, it passes 1650 so you can put it on the end of a PON and shoot through splitters. It does not allow any other wavelenth out that could jam the OLT and cause the PON to go down. Some OTDRs have these filters built in when you are testing on 1650. Also, the filter keeps the p

Does it just need to filter 1310/1490 so the OTDR doesn't see it and then you can shoot 1550? On Wed, Apr 19, 2023 at 3:58 PM wrote: > Just a lump in a fiber jumper with connectors on each end. Would take > some digging to find it. > > > > *From:* Josh Luthman > *Sent:* Wednesday, April 19, 202

Oh I 100% believe they could do it. If I knew tx power of the OTDR it would be easy to estimate how close they’d have to be to exceed the overload threshold of the transceiver. “Dynamic Range” has to be a diff between Tx and sensitivity …..or so I would assume. If it is then I could guess t
