Index Prefix Adjacency

6147 46.228.1.16/29 Unknown Adj

spb-bg3#ping 46.228.1.19

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 46.228.1.19, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms

We can see adjacency is Unknown Adj

What can we do for diagnostic why it is packet has been software switched?

Thanks in advance!

PS:

I can send more information, if it need.
