Why there are two different IP address in a single line during trace?

[vikky sahare]

There are two different IP address in a single line during traceroute but the ip addresses are from same subnet.

[MHM Cisco World]

meaning there are two path, traffic pass different router in each traceroute packet probe
NOTE:- the traceroute command send three probe NOT one probe 
probe one pass through 10.5.247.132 <<- one time appear (ms)
probe two three pass through 10.5.247.133 <<- two time appear (ms)

Hello @vikky sahare,

If you see two IP addresses listed in a single line, it typically indicates that there are multiple paths or routes available between the two network devices. The trace route command may send packets along different paths, and each path may encounter different network devices. As a result, you see multiple IP addresses listed on the same line, representing the various routes that the packets took.

As the others have already described, usually this is due to multiple paths.  Which can happen multiple times to destination.  Usually when this happens, it's between a pair of devices with multiple L3 links.

@MHM Cisco World describes there are 3 probe packets, that is the common default, but often you can change the probe count.  If you can, in this case, try using probe counts of 2 and 4.

@MHM Cisco World also mentions the single hit was on the first probe packet and the dual hit was on the second and third probe packets.  That's possible, but more often a dual hit will be on the first and third probe packets as usually each probe packet is round robined across ECMP.

different between multi hops and round is if the same hop appear in second line 
here there is no round since the hop appear only in one line 

why it appear twice in one hop and once for one hop I think because the  CEF make unequal load balance

"different between multi hops and round is if the same hop appear in second line"

If same IP hop appears in any subsequent line, you've a routing loop.

"here there is no round since the hop appear only in one line"

Didn't write, in this specific instance, this was a case of round robin, just the usual treatment if there's ECMP at that hop.  ECMP can, in this case, be possibly further implied by trying a probe count of 4, 6, 8 or 10, to see if each hop shows equal hits.

"why it appear twice in one hop and once for one hop I think because the  CEF make unequal load balance"

That's possible, increasing probe count may reveal what's the case.
