unnecessary route entry?

Good day Smilie

I recently checked some stuff on my gateway and discovered what I believe is an unneeded route entry.

# route -n
Kernel IP routing table
Destination Gateway Genmask ... Iface
287.265.45.0 0.0.0.0 255.255.255.0 ... eth0
192.168.0.0 0.0.0.0 255.255.255.0 ... eth1
127.0.0.0 0.0.0.0 255.0.0.0 ... lo
0.0.0.0 287.265.45.1 0.0.0.0 ... eth0

The first entry sends packets targeted for the 287.265.45-network directly right (not through another gateway)?

But is this really necessary? Since...

$ traceroute 287.265.45.133
traceroute to 287.265.45.133 (287.265.45.133), 30 hops max, 40 byte packets
1 287.265.45.1 (287.265.45.1) 227.574 ms 12.567 ms 12.8 ms
2 blabla.example.com (287.265.45.133) 2222.17 ms 2719.7 ms 3233.03 ms

... shows that the packets travel through 287.265.45.1 anyway.

[Yes, the ip-adress 287... is invalid, I changed it Smilie ]

Route classifier in tc(8)					       Linux						 Route classifier in tc(8)

NAME
route - route traffic control filter SYNOPSIS
tc filter ... route [ from REALM | fromif TAG ] [ to REALM ] [ classid CLASSID ] [ action ACTION_SPEC ] DESCRIPTION
Match packets based on routing table entries. This filter centers around the possibility to assign a realm to routing table entries. For any packet to be classified by this filter, a routing table lookup is performed and the returned realm is used to decide on whether the packet is a match or not. OPTIONS
action ACTION_SPEC Apply an action from the generic actions framework on matching packets. classid CLASSID Push matching packets into the class identified by CLASSID. from REALM fromif TAG Perform source route lookups. TAG is the name of an interface which must be present on the system at the time of tc invocation. to REALM Match if normal (i.e., destination) routing returns the given REALM. EXAMPLES
Consider the subnet 192.168.2.0/24 being attached to eth0: ip route add 192.168.2.0/24 dev eth0 realm 2 The following route filter will then match packets from that subnet: tc filter add ... route from 2 classid 1:2 and pass packets on to class 1:2. NOTES
Due to implementation details, realm values must be in a range from 0 to 255, inclusive. Alternatively, a verbose name defined in /etc/iproute2/rt_realms may be given instead. SEE ALSO
