Hi,
based on the output:
E3#show ip bgp 181.0.0.0/8 BGP routing table entry for 181.0.0.0/8, version 5 Paths: (1 available, best #1, table default) Not advertised to any peer Refresh Epoch 1 1 2 10.100.1.1 from 2.3.4.5 (11.11.11.11) Origin IGP, metric 0, localpref 100, valid, internal, best rx pathid: 0, tx pathid: 0x0
can somebody explain me:
Refresh Epoch 1
10.100.1.1 from 2.3.4.5 (11.11.11.11)
2.3.4.5 seems to be the neighbor IP Address, 11.11.11.11 is the router-id of the neigbor.
What is 10.100.1.1 ?
Thanks in Advance!
Best regards

Refresh Epoch 1: As the routing protocols start to repopulate the RIB on a prefix-by-prefix basis, the updates in turn cause prefix-by-prefix updates for CEF, which it uses to update the FIB and adjacency databases. Existing and new entries will receive the new version (epoch) number, indicating that they have been refreshed.
"Epoch refers to the period of time"

To answer your 2nd question, 10.100.1.1 is the next hop value. This field will be set to 0.0.0.0 if the prefix is locally originated (for example advertising a loopback address using network statement)
Hope this clarifies

Hi As you mentioned
That is the IP address of IBGP neighbor Peer IP address " 10.100.1.1"
