Secondary IP on Interface

[hernjalukund]

Hello,

In my network, ISP is providing 2 ILL lines with different IP addresses. ILL1-200MB AND ILL2-100MB

BGP IS Configured, but in LAN poolside (customer interface) configured in one interface.

but in LAN both ip not getting the same speed... not configured any policy for lan ip ...we not getting same speed in both IP why ??

Configuration as below 

interface GigabitEthernet0/0
description ILL-SEC
ip address 188.18.20.100 255.255.255.252

interface GigabitEthernet0/1
description ILL-Pri
ip address 188.18.20.150 255.255.255.252

interface GigabitEthernet0/2
description ***For-Customer***
ip address 100.120.18.110 255.255.255.248 secondary
ip address 100.122.16.49 255.255.255.252

NOW issue is 

in IP pool 100.122.16.49 we get only 100Mbps speed and

in IP pool 100.120.18.110  we get only 200Mbps speed...

Hello @hernjalukund 

By default, BGP will use both ILL lines to balance the traffic. However, the load may not be distributed evenly between the two lines. As a result, one IP pool may receive more traffic than the other, causing slower speeds.

Also, you can use monitoring tools to check the utilization of each ILL line. If one line is experiencing high utilization, it may be causing the slower speed on the IP pool associated with that line.

can you select any prefix you receive from BGP peer 
do 
show ip bgp x.x.x.x <<- share it here

@hernjalukund  Could you share "show ip bgp" and "sh ip route" output here?
