Bug ID: 264722
Summary: Incorrect source address used in non default fib
Product: Base System
Version: 12.3-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
Using a non-default fib, the source address used in ipv4 packets is 0.0.0.0.
Routing tables
Internet:
Destination Gateway Flags Netif Expire
default 10.78.2.1 UGS eth0
10.78.2.0/24 link#2 U eth0
10.78.2.104 link#2 UHS lo0
127.0.0.1 link#1 UH lo0
172.17.1.0/24 link#3 U eth1
172.17.1.2 link#3 UHS lo0
Routing tables (fib: 1)
Internet:
Destination Gateway Flags Netif Expire
default 10.78.2.1 UGS eth0
10.78.2.0/24 08:00:27:3b:12:12 US eth0
10.78.2.104 lo0 UHS lo0
127.0.0.1 lo0 UHS lo0
172.17.1.0/24 00:15:5d:02:30:0d US eth1
172.17.1.2 lo0 UHS lo0
The following command works correctly:
setfib 0 ping 172.17.1.4
This command generates ICMP packets with 0.0.0.0 as the source IP:
setfib 1 ping 172.17.1.4
While I can't rule out setup issues, this used to work correctly in FreeBSD
12.2.
