Hi,
My ISR 4451X/K9 with  (  Through Put 2G , Foundation Suite K9, AdvUc Suite K9  Perpetual License)

When I config   Routing Protocol BGP  , Connection with  ISP Directly   and IP Transit Network,   Actual Wan Speed is Over 800mbps . when i  used to test  wan speed output only 200 mbps (via fast.com) . help me to find out.  thank a lot.

Interface  I used in ISR as follows:

GI0/0/0 -> WAN to ISP BGP link

GI0/0/3 -> Connection to Router (Mikrotik CCR1036)

Current connection:

ISR <->Mikrotik1036<->LAN  ====> speedtest 200 Mbps around

Earlier connection:

Mikrotik2004<->Mikrotik1036<->LAN =====> speedtest 700-800+ Mbps ( wanna change with 2004 to  ISR 4451)

ISR BGP config :

run | begin bgp
router bgp xxxxx
bgp router-id xxx.xxx.xx.xxx
bgp log-neighbor-changes
beg bestpath as-path multipath-relax
neighbor 203.xxx.xx.xxx remote-as xxxx

neighbor 203.xxx.xx.xxx password
neighbor 203.xxx.xx.xxx version 4

address-family ipv4
network 103.xxx.x.x mask 255.255.255.0

network 103.xxx.1.x mask 255.255.255.0
redistribute connected

neighbor 203.xxx.xx.xxx activate
neighbor 203.xxx.xx.xxx soft-reconfiguration inbound

 200 mbps like what u get with  100 mbps and full duplex; somthing is not set up right; start with cable, make sure is OK and CAT5e or 5; check speed and duplex settings; check port and router QoS if any configured, it may reduce speeds/bandwodth.

Dear Martin,

I used with SFP 1G+ cable and already check  cabling.  its not  cable problem.  when i test with   ISP > IRS > Mikrotik CCR 1036 , connection normal,  but test with speed test and download  are  stop at 200 mbps.  My actual connection was around 700-800 mbps.  How do i configure at  ISR 4451-X/K9. Please lead me to solution .

Best Regards,
