Hi, i have a CCR1072-1G-8S+ running BGP and Ospf as internal, the router drop down all Ospf peers at the same time, this has happened to someone else?

The interface is not disconecting and not lose L2 comunication when occurs....

Hello Leonardorortizm,

What version of RouterOS are you using on the CCR1072-1G-8S+ ?

Hi, im using v6.49.5 RouterOs

how your NAT looks like?

Hi mate , thanks for write, i have solve it.

The problem was CPU usage over 75%. I was thinking that for an router too big as CCR1072 75% was'nt much.-

Hi, the problem has occurred again with cpu usage in 33%, i don't now what i can do for solve it!.

I have other two CCR1072 with the same configuration without problems

This is my NAT

9 ;;; NAT
chain=srcnat action=same to-addresses=(BGP Public range) same-not-by-dst=yes
protocol=!ospf src-address-list=Zarzal dst-address-list=!LAN log=no log-prefix=""

10 ;;; NAT
chain=srcnat action=same to-addresses=(other BGP Public range) same-not-by-dst=yes
protocol=!ospf src-address-list=ITX-RUTA-CRUZ dst-address-list=!LAN log=no log-prefix=""

let see what the log saying:



/system logging action
add name=ospf target=memory

/system logging
add action=ospf topics=ospf

This is the log file:

https://drive.google.com/file/d/1MJiIO6 ... sp=sharing

ospf doing what supposed to be doing

Things to check:

Duplicated router ids
Areas and types
Network Type

you mentioned above that you are experiencing high CPU, is that because of ospf? how about if u disable it.
can we get export file?

have u checked maybe / tool profile

Not sure if this is your issue, but see this thread: viewtopic.php?t=116968

@nichky
thanks, i will be reviewing your suggestions.
About cpu usage was solved reducing the amount of traffic that was being sent by mangle routing mark (3GB).

When the cpu usage was high /tool profile shows: routing and firewall are the most that consuming cpu.

Ok i understand that i can have a problem with Ospf, but this not explain why the router is killing BGP too.

@UplinkLLC

It has not worked for me.

once u get high CPU
check / tool profile and show us here

The cpu was not high anymore

this is when router is down

Same problem unsolved here

viewtopic.php?t=122671

I has solved the issue, the problem was that the router has receiving an high amount of updates by BGP protocol (about 2 Millions) , the router can't manage this and them kill the BGP process, BGP and OSPF runs under the same process, for this reason all is down when occurs.

the solve was to talk with internet provider and request that only sends to me the default gateway.

I'm not convenced that Mikrotik 1072 could manage Full Routing BGP. Support has said that update to RouterOs V7 could solve the initial issue.

Hello,

Mark the problem as solved please.

Thank you,
